Using Hook to skip Evidence Sharing on Case/Case Member Creation

The new hook is provided to stop evidence sharing on case/case member creation process and restart at the later stage if required.The API stopSharing() and restartSharing() in curam.evidencebroker.sl.intf.EvidenceBroker.java supports stop and restarting evidence sharing process. Evidence Broker triggers evidence sharing based on the 'StopEvidenceSharing' flag. stopSharing() API sets the 'StopEvidenceSharing' flag which skips evidence sharing in Evidence Broker and the API should be called at the start of case/case member creation process.Evidence sharing can be restarted by invoking restartSharing() API which resets the 'StopEvidenceSharing' and allows the evidence sharing to proceed in case/case member creation process.
