[ASTERIXDB-2103][STO] Too many disk components for CorrelatedPolicy

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

Details:
Currently CorrelatedMergePolicy uses component Ids to ensure disk
components of primary and secondary indexes are merged together,
but without synchronization. However, this results in too many disk
components for secondary InvertedIndex. The reason is that when the
policy finds some secondary index is being merged, it will temporarily
ignore that secondary index. Since mering InvertedIndex is slow, it's
thus possible that it misses merges over and over again, causing too
many components on disk.

This patch fixes this bug by:
- Add dependingMerges to MergeOperation. A MergeOperation finishes
only after all depending merges have finished.
- Inside CorrelatedMergePolicy, the merge of the primary index depends
on all merges of secondaries indexes. This ensures the merge of the
primary index will be the last one to finish.
