* Corrected client session handling to make internal IPC socket persistent

Browse source 
* Applies to cli/netconf/restconf/client-api code
  * Previous behaviour:
    * Close socket after each rpc, but now keeps the socket open until the client terminates
    * Kept locks over socket life-cycle, but according to RFC 6241 7.5 a lock should be relaeased when session ends
