[ASTERIXDB-2541][STO] 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.

[ASTERIXDB-2540][STO] Optimize Storage Disk I/O

- user model changes: yes. Add a new storage option:

storage.disk.force.bytes (default 16MB),

- storage format changes: no.

- interface changes: yes.

Introduced IPageWriteCallback to LSM indexes

Details:

- Bypass all queuing (from BufferCache and IOManager) for disk writes.

This queuing is unnecessary but destroys fairness among multiple

writers.

- Introduce IPageWriteCallback to control the behavior of disk page

writes. Currently, this interface is used to perform disk forces

regularly for each writer thread.
