--------------------------------------------------------
Patch 001 includes:
- Add an new interface: DiskValidator
- Add two classes to implement the interface: BasicDiskValidator and
ReadWriteValidator, BasicDiskValidator invokes the existing DiskChecker. And
ReadWriteValidator doesn't do anything right now, might make it functional in
next JIRA.
- Add one configuration in YarnConfiguration to indicate which DiskValidator
Yarn want to use.
- Migrate two callers of DiskChecker in YARN NodeManager to use new pluggable
disk checker.

> It would be nice to have the option for a DiskChecker that has more
> sophisticated checking capabilities. In order to do this, we would first
> need DiskChecker to be pluggable.
