Snapshot metrics stop getting scheduled in an exception occurs

Hi Samza devs,

I ran into an issue with Samza 0.9.1 where I had a serialization exception
thrown in the MetricsSnapshotReporter.  It's very hard to find because
nothing is logged and the metrics just stop getting scheduled.  Samza
should catch all exceptions in that thread, log them, and suppress them
rather than no longer scheduling snapshot metrics at all.

JIRA filed here:

Cheers,

Roger
