if your server is built to make drpc connections, clients can
still connect with grpc. thus, your responses to grpc clients
must still look the same, so we have to have all of our status
wrapping include codes for both the drpc and grpc servers to
return the right thing.

these may not be optimal but they're probably better based on
our previous testing. we can tune better in the future now that
the groundwork is there.

We don't use reverse listing in any of our code, outside of tests, and
it is only exposed through libuplink in the
lib/uplink.(*Project).ListBuckets() API. We also don't know of any users
who might have a need for reverse listing through ListBuckets().
Since one of our prospective pointerdb backends can not support
backwards iteration, and because of the above considerations, we are
going to remove the reverse listing feature.

drpc will call Close on any transport we pass to it, but some
transports (like tls.Conn) will attempt to notify the remote
side of things. we don't want to do that, so pass a new
interface that just closes the underlying socket.

Change signature of metainfo DeleteObject to get rid of an extra call to
kvmetainfo GetBucket method and eliminate one round trip to the
satellite when deleting objects.
grpc doesn't exit dials right away if the context dialer
returns an error. since that's the only spot where we were
enforcing dial timeouts, dials could just leak for an
unknown amount of time.
add a timeout above the grpc dial because that's the documented
way that grpc expected to be canceled.

keep a pool of connections open when dialing for drpc. this
makes it so that long lived clients (like lib/uplink's Project)
don't continue to use a bad connection forever. it also allows
for concurrent rpcs.

libuplink was incorrectly setting timeouts to 10 seconds still, but
should have been at least 10 minutes. the order sender was setting them
to 1 hour. we don't want timeouts in uplink-side logic as it establishes
a minimum rate on tcp streams.
instead of all of this, just use tcp keep alive. tcp keep alive packets are
sent every 15 seconds and if the peer stops responding the connection
dies. this is enabled by default with go. this will kill tcp connections
when they stop working.

What:
Bring back partial nodeID to debug.trace-out
Why:
The information is useful for interpreting the trace file and was there up drpc. I just bring it back.

This change adds a trusted registry (via the source code) of node address to node id mappings (currently only for well known Satellites) to defeat MITM attacks to Satellites. It also extends the uplink UI such that when entering a satellite address by hand, a node id prefix can also be added to defeat MITM attacks with unknown satellites.
When running uplink setup, satellite addresses can now be of the form 12EayRS2V1k@us-central-1.tardigrade.io (not even using a full node id) to ensure that the peer contacted is the peer that was expected. When using a known satellite address, the known node ids are used if no override is provided.
we spawned a goroutine to wait on the context's done
channel sending the error afterward, but we forgot
to ensure the context was eventually done, so the
goroutine would be leaked until then.
instead, we can just do a select on two channels to
get the error rather than spawn a goroutine which
makes it impossible to leak a goroutine.

the net package does not make it easy to know if DialContext
failed because the context was done. it's important for some
of our tests that canceled contexts are detected as such, so
we accept the small race that's arguably correct (the context
must be canceled asynchronously) to ensure we always return
the context error if available.

all of the packages and tests work with both grpc and
drpc. we'll probably need to do some jenkins pipelines
to run the tests with drpc as well.
most of the changes are really due to a bit of cleanup
of the pkg/transport.Client api into an rpc.Dialer in
the spirit of a net.Dialer. now that we don't need
observers, we can pass around stateless configuration
to everything rather than stateful things that issue
observations. it also adds a DialAddressID for the
case where we don't have a pb.Node, but we do have an
address and want to assert some ID. this happened
pretty frequently, and now there's no more weird
contortions creating custom tls options, etc.
a lot of the other changes are being consistent/using
the abstractions in the rpc package to do rpc style
things like finding peer information, or checking
status codes.

it was possible, because we spawned Run before we did any calls
to Route, that the listenmux would send multiple connections to
the default listener. Fix that by ensuring we call Route before
we call Run.
Change-Id: Ie8fd754997975969a99fd2a3f8d3010c24cdc73d
It provides an abstraction around the rpc details so that one
can use dprc or gprc with the same code. It subsumes using the
protobuf package directly for client interfaces as well as
the pkg/transport package to perform dials.

What:
cmd/inspector/main.go: removes kad commands
internal/testplanet/planet.go: Waits for contact chore to finish
satellite/contact/nodesservice.go: creates an empty nodes service implementation
satellite/contact/service.go: implements Local and FetchInfo methods & adds external address config value
satellite/discovery/service.go: replaces kad.FetchInfo with contact.FetchInfo in Refresh() & removes Discover()
satellite/peer.go: sets up contact service and endpoints
storagenode/console/service.go: replaces nodeID with contact.Local()
storagenode/contact/chore.go: replaces routing table with contact service
storagenode/contact/nodesservice.go: creates empty implementation for ping and request info nodes service & implements RequestInfo method
storagenode/contact/service.go: creates a service to return the local node and update its own capacity
storagenode/monitor/monitor.go: uses contact service in place of routing table
storagenode/operator.go: moves operatorconfig from kad into its own setup
storagenode/peer.go: sets up contact service, chore, pingstats and endpoints
satellite/overlay/config.go: changes NodeSelectionConfig.OnlineWindow default to 4hr to allow for accurate repair selection

storagenode/inspector/inspector.go
storagenode/peer.go
storagenode/storagenodedb/database.go
Why: Replacing Kademlia
Please describe the tests:
• internal/testplanet/planet_test.go:
TestBasic: assert that the storagenode can check in with the satellite without any errors
TestContact: test that all nodes get inserted into both satellites' overlay cache during testplanet setup
• satellite/contact/contact_test.go:
TestFetchInfo: Tests that the FetchInfo method returns the correct info
• storagenode/contact/contact_test.go:
TestNodeInfoUpdated: tests that the contact chore updates the node information
TestRequestInfoEndpoint: tests that the Request info endpoint returns the correct info
Please describe the performance impact: Node discovery should be at least slightly more performant since each node connects directly to each satellite and no longer needs to wait for bootstrapping. It probably won't be faster in real time on start up since each node waits a random amount of time (less than 1 hr) to initialize its first connection (jitter).

What: we move api keys out of the grpc connection-level metadata on the client side and into the request protobufs directly. the server side still supports both mechanisms for backwards compatibility.
Why: dRPC won't support connection-level metadata. the only thing we currently use connection-level metadata for is api keys. we need to move all information needed by a request into the request protobuf itself for drpc support. check out the .proto changes for the main details.
One fun side-fact: Did you know that protobuf fields 1-15 are special and only use one byte for both the field number and type? Additionally did you know we don't use field 15 anywhere yet? So the new request header will use field 15, and should use field 15 on all protobufs going forward.
Please describe the tests: all existing tests should pass

The fundamental problem is that both drpc and grpc servers
want to close the listener and they both want to ignore the
error from Accept after the listener is closed. There's no
way to do this in a race free way. Fortunately, the mux
hands out listeners that can be independently closed. That
means they can both do their own shutdown logic where they
ignore the error, and then after they're closed, the code
orchestrating the servers can close the listeners.
The final weird bit is that the server's Close method is
required to wait until the Run method has exited (or at
least enough for the listeners to definitely be closed)
because tests depend on that behavior, so we have to add
some channels/mutexes/onces to ensure that Run has exited
and that a new call can't start after Close is called.

the current prometheus help messages have enough unexpected

What: this change makes sure the count of segments is not encrypted.
Why: having the segment count encrypted just makes things hard for no reason - a satellite operator can figure out how many segments an object has by looking at the other segments in the database. but if a user has access but has lost their encryption key, they now can't clean up or delete old segments because they can't know how many there are without just guessing until they get errors. :(
Backwards compatibility: clients will still understand old pointers and will still write old pointers. at some point in the future perhaps we can do a migration for remaining old pointers so we can delete the old code.

* pkg/process: Fatal show complete error information
Change the general process execution function to not using the sugared
logger for outputting the full error information.
Delete some unreachable code because Zap logger Fatal method calls exit

* storagenode/storagenodedb: Add info to error
Add more information to an error returned due to some data
inconsistency.
* storagenode/orders: Don't use sugared logger
Don't use sugar logger and provide better contextualized error messages
in settle method.
* storagenode/orders: Add some log fields to error msgs
Add some relevant log fields to some logged errors of the sender settle
method.
* satellite/orders: Remove always nil error from debug
Remove an error which as logged in debug level which was always nil and
makes the logic that used this variable clear.
* storagenode/orders: Don't return error Archiving unsent
Don't stop the process which archive unsent orders if some of them
aren't found the DB because it cause the Storage Node to stop with a
fatal error.
this avoids a problem where setting on a flag isn't sufficient
to express complex data structures like []string.
