  Talked to Kevin offline - no need to add appliedSystemProperties in conf.

  Also, can you add a big comment in SessionState explaining overriddenConfigurations

> It would be useful to keep track of which config variables the user has explicitly changed from the values which are either default or loaded from hive-site.xml.  These include config variables set using the hiveconf argument to the CLI, and via the SET command.  This could be used to prevent Hive from changing a config variable which has been explicitly set by the user, and also potentially for logging to help with later debugging of failed queries.
