> We need to be able to set logging per HS2 session.
> The client often uses the map-reduce completion matrix (Execution) that shows up in Beeline
to debug performance. User might not want the verbose log view all the time since it obfuscates
the Execution information. Hence the client should be able to change the verbosity level.
> Also, there are 2 levels of verbosity at HS2 logging and not 3. The users might want
Execution + Performance counters only - so that level needs to be added.
> So for logs,  the user should be able to set 3 levels of verbosity in the session, that
will override the default verbosity specified in the hive-site.xml file.
> 0. None - IGNORE
> 1. Execution - Just shows the map-reduce tasks completing 
> 2. Performance - Execution + Performance counters dumped at the end
> 3. Verbose - All logs
