[ASTERIXDB-2552][RT] Reuse objects on reseting buffer manager
- user model changes: no
- storage format changes: no
- interface changes: yes
Details:
The "VariableFrameMemoryManager" releases the physical frames
objects, the logical frames objects and the free slots objects
on reset(). This patch is to retain those objects and only
release them on close() (as also stated in the interface).
- added close() to IFrameFreeSlotPolicy to make the interface similar
to the other interfaces (IFrameBufferManager, IFramePool, ... etc)
where close() is supposed to release while reset() is supposed to only
reset but retain resources.
- renamed "InMemorySortRuntimeFactory" to "MicroSortRuntimeFactory".

> Assignee: Ali Alsuliman
> Priority: Major
> Fix For: 0.9.4.2

> However, the sort operator that is used in subplans currently is in memory
> sort and not an external sort and thus could run out of memory.
