[ASTERIXDB-2688][HYR] Fix use of a Hyracks task across join stages

- user model changes: no
- storage format changes: no
- interface changes: yes

Details:
In hash join, a task from the build stage is being used in the probe stage.
This is a problem since such tasks have already finished and notified the CC they are done.
One observed issue is related to issuing a warning in the probe phase where some warnings are
not reported because they are issued to tasks that have finished (the way this happened is that
a comparator was created in the build phase using the build-phase task. Then, this comparator
was used in the probe phase and issued a warning).

- make IHyracksJobletContext extend IHyracksCommonContext so that it is also a frame manager context
- make activites of join operators use the joblet context instead of the task context for acquiring buffers
- create the probe-to-build comparator in the probe phase so that the right task is used in the comparator
