[ASTERIXDB-2552][RT] Implement micro external sort for subplans

- user model changes: no

- storage format changes: no

- interface changes: no

Details:

This patch is to change the in memory sort used in subplans to

be a micro external sort to avoid out of memory error.

- added reset() to the runs merger to allow reusing the runs merger.

- renamed "InMemoryStableSortPOperator" to "MicroStableSortPOperator".

- changed the tag from "IN_MEMORY_STABLE_SORT" to "MICRO_STABLE_SORT".

- added test cases.
