Review Comment:
   This config was added to remove the hardcoded sleep time in the code, also 
to avoid extensive sleep time while unit test are executed.

> After catching the exception generated by the findNextCompactionAndExecute() 
> task, HS2 appears to immediately rerun the task with no delay or backoff.  As 
> a result there are ~3500 connection attempts from HS2 to HMS over just a 5 
> second period in the HS2 log
> The compactor.Worker should wait between failed attempts and maybe do an 
> exponential backoff.
