ENG-4942 Initial work to log HASH MISMATCH. Need to find a way to test and does additional info needs
to be sent around?
Update RECOVERYING msg
added safe snapshot restore
removed whitespace
Fixes after review.
Merge branch 'master' into ENG-4917
Check for null in SpScheduler
Dont let FragmentMessage lookup procedureName as its not there for subsequent batches.
Also HASH MISMATCH is expected to be impossible to happen in Sp with Fragment messages.
Make compiler report timestamp include timezone.
Add comment for non-determinism and procedurename as a signal.
Make the Thread.sleep() on shutdown 3000 times shorter.
Should make tests run faster.
