Either one of the 2 commits fixes the problem with the tests taking too
long. This first one makes it so metrics are actually reported back in local
mode, which will help with tests in the future.
The second commit decouples the metrics reporting from the slot state
machine path, so it will not block when trying to communicate with nimbus, for
example if nimbus is down.---
