> Extensions using Hive session handles should be able to restore the hive session from the handle. 
> Apache Lens depends on a fork of hive and that fork has such a capability. 
> Relevant commit: https://github.com/InMobi/hive/commit/931fe9116161a18952c082c14223ad6745fefe00#diff-0acb35f7cab7492f522b0c40ce3ce1be
> Functionality added: Restoring a session. A session opened once is lost once the cli service is restarted. There may be some operation going on in that session at the time the service is restarted. It's useful to be able to restore a previously existing session. 
> Have added code in CLIService for that effect. Have also added a test class.
