Daniel Nephin f0ac093fef agent/grpc: add connection count metrics
Gauge metrics are great for understanding the current state, but can somtimes hide problems
if there are many disconnect/reconnects.

This commit adds counter metrics for connections and streams to make it easier to see the
count of newly created connections and streams.

Daniel Nephin 5319ba02b0 agent/grpc: rename metrics
These new names should make it easier to add counter metics with similar prefixes

Daniel Nephin 8a785a351c agent/grpc: pass metrics to constructor
Instead of referencing a package var. This does not fix the flaky test, but it seems more correct.

Daniel Nephin 636f76f6f1 agent/grpc: make TestHandler_EmitsStats predictable
Occasionally this test would flake. The flakes were fixed by:

1. Stopping the service and retrying to check on metrics. This way we
   also include the active_streams going to 0 in the metric calls.

2. Using a reference to the global Metrics. This way when other tests
   have background goroutines that are still shutting down, they won't
   emit metrics to the metric instance with the fake Sink. The stats
   test can patch the local reference to the global, so the existing
   statHandlers will continue to emit to the global, but the stats
   test will send all metrics to the replacement.
