> In this JIRA we'll design two interfaces:
> * SparkSessionState
> * SparkSessionPoolManager
> and then once that is agreed upon we'll design two implementations:
> * SparkSessionStateImpl
> * SparkSessionPoolManagerImpl
> the form and function of these will be similar to the Tez equivalents. 
> However, TezSessionState provides some implementation which SparkClient 
> already provides (refreshLocalResources*). Let's keep SparkSessionState 
> lightweight and not remove functionality from SparkClient. The scope of this 
> jira is just to create the shells and basic functionality. The 
> implementations in this jira should be able to:
> * Share a SparkSessionImpl across queries
> * Defining when a session can be re-used
> * Take ownership of SparkContext objects (Note we can only have a single SC 
> until SPARK-2243 is resolved)
