ea1c28d61d
Implement asynchronous job management to ensure jobs can be successfully completed even if those jobs temporally fail for some reasons. The detailed design can be found in section 9 in design document. This patch focuses on enabling workers to rerun failed job. Workers started with configuration option 'periodic_enable' set to 'True' are responsible to this work. Purging old job records will be covered in later patches.
