Gh-3096: JobTracker Performance Improvement

[tb06904]

Various improvements to the Job Tracker (and subsequently the cache) to hopefully address some of the performance issues. There may be other areas but the main changes and rational behind them are:

• Move the Cache interface to be more generic Iterator instead of Set this should allow Cache implementations to do lazy gets so process wont block on loading everything into memory first.
• Configurable Job rescheduling on start up, this allows users to control whether they want to reschedule all jobs in the Cache on start up or not as this can have a large impact on start up times (its off by default).
• Adding to the JobTracker cache is now async to not block the main operation, gets are still synced to prevent concurrent modifications.
• Minor fix to add short circuit logic to the NamedOperationCache so that it doesn't always do a get all if overwrite is disabled.
• Few minor bits of refactoring to help maintenance.

Once performance tests are in place they should verify if improvements have made substantial difference.
