* chore: Fix flaky metrics tests (#1865)

This fixes a few flaky unit tests that relied on `Thread.sleep` to ensure that all metrics processing was done.  Rather than using `Thread.sleep`, we can instead use an inline event queue in the OpenCensus stats component to execute all work inline, removing the need to wait for anything to finish.
