This will apply an appropriate "subsystem" label to goroutines which are
part of the core, api, repairer, admin, or gc subsystems.
It will also label goroutines whose job it is to watch for slow shutdown
of lifecycle groups (there are a lot of these).
Finally, this will also label goroutines whose job it is to wait on the
toplevel errgroup of a subsystem.

When services take long to shutdown it's useful to get a stack trace for
diagnosing the underlying problem.

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.
