Change in asterixdb[master]: [ASTERIXDB-2541] Introduce GreedyScheduler

["Luo Chen (Code Review)" <de...@asterixdb.apache.org>]

Hello Anon. E. Moose (1000171), Till Westmann, Jenkins, Michael Blow, Murtadha Hubail, Ian Maxon, 

I'd like you to reexamine a change. Please visit

    https://asterix-gerrit.ics.uci.edu/3284

to look at the new patch set (#5).

Change subject: [ASTERIXDB-2541] Introduce GreedyScheduler
......................................................................

[ASTERIXDB-2541] Introduce GreedyScheduler

- user model changes: yes.
   Add new option: storage.io.scheduler (async/greedy)
- storage format changes: no.
- interface changes: yes.
  Introduce IIndexCursorStats

Details:
- Introduce GreedyScheduler that always executes the merge
operation with the smallest number of remaining pages to minimize
the number of disk components
- Introduce IIndexCursorStats to collect the statistics of index scans.
This allows GreedyScheduler to know the remaning pages of merge
operations.
- Extend AbstractIoOperation so that GreedyScheduler can pause/resume
merge operations if needed.
