The current implementation blocks the the startup until one or none
of the trusted satellites is able to reach the node via QUIC.
This can cause delayed startup. Also, the quic check is done
once during startup, and if there is a misconfiguration later,
snos would have to restart to node.
In this change, we reuse the contact service which pings the satellite
periodically for node checkin. During checkin the satellite tries
pinging the node back via both TCP and QUIC and reports both statuses.
WIth this, we are able to get a periodic update of the QUIC status
without restarting the node.
Also adds the time the node was last pinged via QUIC to the tooltip
on the QUIC status tab.

errs.Class should not contain "error" in the name, since that causes a
lot of stutter in the error logs. As an example a log line could end up
looking like:
ERROR node stats service error: satellitedbs error: node stats database error: no rows
Whereas something like:
ERROR nodestats service: satellitedbs: nodestatsdb: no rows
Would contain all the necessary information without the stutter.

QUIC
We want to encourage storagenodes to open their udp port. This PR
changes contact service in satellite to try to connect to nodes through
QUIC. If satellite can't reach nodes through quic, it will send an error
message back to nodes. On the nodes side, it will always log out error
message from check in if the error message is not empty.
Whether satellite can reach nodes through quic has no affect on nodes'
uptime check.

If the satellite fails to pingback the storage node during CheckIn
an error message is returned to the node in the response, but the actual
error value returned is nil. We are only checking the error. This means
the node has no feedback about the failure, and the node also does not
attempt to retry the connection.

Most places now need the NodeURL rather than the ID and Address
separately. This simplifies code in multiple places.

When a storagenode begins to run low on capacity, we want to notify
the satellite before completely running out of space. To achieve this,
at the end of an upload request, the SN checks if its available space has
fallen below a certain threshold. If so, trigger a notification to the
satellites.
The new NotifyLowDisk method on the monitor chore is implemented using the
common/syn2.Cooldown type, which allows us to execute contact only once
within a given timeframe; avoiding hammering the satellites with requests.
This PR contains changes to the storagenode/contact package, namely moving
methods involving the actual satellite communication out of Chore and into
Service. This allows us to ping satellites from the monitor chore

this commit updates our monkit dependency to the v3 version where
it outputs in an influx style. this makes discovery much easier
as many tools are built to look at it this way.
graphite and rothko will suffer some due to no longer being a tree
based on dots. hopefully time will exist to update rothko to
index based on the new metric format.
it adds an influx output for the statreceiver so that we can
write to influxdb v1 or v2 directly.

When the contact chore starts running before the monitor service has
provided any useful capacity data, the first outgoing contact has
not-very-helpful data for the satellite. This change causes the contact
chore to wait until capacity data is available. The wait should be quite
short in all reasonable cases: even when a node starts with a lot of
stored pieces and no cached spaceUsedDB data, new data will have been
calculated and cached by the call to
`peer.Storage2.CacheService.Init(ctx)` in `storagenode.cmdRun()` before
`peer.Run(ctx)`.

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
Removes kademlia setups in:
cmd/storagenode/main.go
cmd/storj-sim/network.go
internal/testplane/planet.go
internal/testplanet/satellite.go
internal/testplanet/storagenode.go
satellite/peer.go
scripts/test-sim-backwards.sh
scripts/testdata/satellite-config.yaml.lock
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).
