[ASTERIXDB-2738][STO] Create Mask File Before Merge Operations

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

Details:
- Before starting a merge operation, create a mask file
  (.mask_C_startSeq_endSeq) for the merged component to
  indicate that this component isn't valid yet.
- On the merge operation successful completion, delete the
  merged component mask file.
- In the case of any unexpected failure during the merge
  operation, all files of the failed merged component will
  be deleted on node startup/shutdown, including the mask
  file.
- Halt on any IO opeartion failure.
- Add a test case that ensures only masked merged components
  are deleted but not the original components that were
  supposed to be merged.
