cmd/coordinator: migrate to OpenCensus for metrics

Replace low-level Stackdriver monitoring API usage for OpenCensus
with a Stackdriver exporter. To benefit local development, expose
metrics at an /metrics endpoint (to be picked up with Prometheus).

This makes it much easier to add new metrics, to test them locally,
and brings our metrics solution in sync with what's currently in
use in x/playground (see CL 302769). It's expected to be preferable
to migrate to OpenTelemetry in the future when a good migration path
becomes available, and both x/build and x/playground can be updated
at that time.

This CL is based on work in CL 229679 and CL 138522.

For golang/go#26779.
For golang/go#44406.
For golang/go#17104.
