IMPALA-2550: Switch to per-query exec rpc

Coordinator:
- FragmentInstanceState -> BackendState, which in turn records
  FragmentInstanceStats

QueryState
- does query-wide setup in a separate thread (which also launches
  the instance exec threads)
- has a query-wide 'prepared' state at which point all static setup
  is done and all FragmentInstanceStates are accessible

Also renamed QueryExecState to ClientRequestState.

Simplified handling of execution status (in FragmentInstanceState):
- status only transmitted via ReportExecStatus rpc
- in particular, it's not returned anymore from the Cancel rpc

FIS: Fixed bugs related to partially-prepared state (in Close() and ReleaseThreadToken())
