> Add samza-rest manager that periodically cleans up the stale local stores of
> dead jobs/tasks.
> It performs the store deletion in two phases. Initially it deletes the offset
> file in the local task stores if the following condition is true.
> ((jobIsNotRunning || preferedHost != nmHost) && offsetFilelastModifiedTime is
> greater than deleteRetention).
> During the subsequent run, it deletes the local task stores if it does not
> contain offset file.
> Refer to the design doc of SAMZA-656
> (https://issues.apache.org/jira/secure/attachment/12828083/DESIGN-SAMZA-656.pdf)
> for more details.
