this is to help protect against intentional or unintentional
slowloris style problems where a client keeps a tcp connection
alive but never sends any data. because grpc is great, we have
to spawn a separate goroutine for every read/write to the stream
so that we can return from the server handler to cancel it if
necessary. yep. really.
additionally, we update the rpcstatus package to do some stack
trace capture and add a Wrap method for the times where we want
to just use the existing error.
also fixes a number of TODOs where we attach status codes to the
returned errors in the endpoints.

This reverts commit 8e242cd012.
Revert because lib/pq has known issues with context cancellation.
These issues need to be resolved before these changes can be merged.

this will allow for some nice runtime analysis down the road.
also, this allows for wrapping database handles in a way that
can interact with these contexts

Adds check to see if storage nodes are eligible to initiate
graceful exit, by checking their CreatedAt date and seeing if
their "age" is greater than the new config value:
NodeMinAgeInMonths
The default for this value is 6 months for now.

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.

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.

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.

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.

What: Change cmd/uplink to use scopes
It moves the fields that will be subsumed by scopes into an explicit legacy section and hides their configuration flags.
Why: So that it can read scopes in from files and stuff
