DRILL-5963: Query state process improvements
1. Added two new query states: PREPARING (when foreman is initialized) and
PLANNING (includes logical and / or physical planning).
2. Process of query enqueuing was made non-blocking. Once query was
enqueued, fragments runner is called to submit fragments locally and remotely.
3. Ability to cancel query during planning and enqueued states was added.
4. Logic for submitting fragments was moved from Foreman to new class
FragmentsRunner.
5. Major type in DrillFuncHolderExpr was cached for better performance.
