Improved Session Management During S-GW Restoration

Previous Behavior: During S-GW Restoration, when the S-GW has recovered and starts reusing same TEID range for
GTPU sessions prior to restart, the S-GW did not properly clear GTPUMGR sessions and GTPU ECHO messages
continued to be sent.

New Behavior:When entering the S-GW Restoration State, GTPUMGR session entries are now cleared and the S-GW
will stop GTPU ECHO messages towards the peer S-GW.

GTPU session entities will be re-built upon recieving a MBReq to recover the sessions.

GTPUMGR will drop ERROR_IND if the session is in S-GW Restoration State.
