Subject [Impala-ASF-CR] IMPALA-4014: Introduce query-wide execution state.

Change subject: IMPALA-4014: Introduce query-wide execution state.
......................................................................


Patch Set 11:

>From the discussion today:

Points agreed on:
 - Collapse Executors and states, i.e. collapse FragmentInstanceExecutor into FragmentInstanceState,
so that responsibilities and boundaries of classes are clear.

 - QueryExecMgr is still responsible for setting up the QueryState and creating the fragment
threads for now. Once the per-query RPC is implemented, the model will change such that QueryExecMgr
creates a “query" thread which sets up the QueryState and starts the fragment threads.

Additionally, I'll put out a separate patch with *only* headers that are parallel with the
existing headers, so that Lars can use that to work on the per-query RPC.
