Jimmy Zelinskie 4bf4ce33c9 util/metrics: remove metricqueue abstraction
This change replaces the metricqueue library with a native Prometheus
client implementation with the intention to aggregated results with the
Prometheus PushGateway.

This change also adds instrumentation for greenlet context switches.
