Instead of using the expiring cache type as a means to store worker information just avoid using that type since we don't support expiry in the first place on worker information and use a worker container and a worker object that we can later extend as needed. Also add on clear methods to the cache type that will be used when the WBE executor stop occurs. This ensures we clear out the worker information and any unfinished requests.
