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

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


Patch Set 1:

This addresses all the header comments in the non-header only patch:
(i.e. https://gerrit.cloudera.org/#/c/3817/)

I will post a compilable version of this patch in that CR. That will be a lot more tricky
mainly because:
 - PlanFragmentExecutor and FragmentExecState are now one class. This makes the coordinator
code tricky because the Coordinator had special code which depended only on the PFE and not
on the FES; and has redundant FES functionality to manage the PFE.

@Lars: This patch can be used as a guide for the per-query RPC (IMPALA-2550), and also for
working out the final kinks in the headers.
