Refactoring datastore package
Preparation to make datastore replacable
- Extract datastore interfaces
- Add multi Read/Write/Remove
- Add a method to walk over RCTable
- Refactor serialize/deserialize RCObject
- Localize dependency to JRAMCloud
- Separate RAMCloud specific code into ramcloud package
- Remove dependency to RAMCloud exception classes
- Remove RC prefix from non RAMCloud specific code
- Cosmetics and update sample/test code
- reflect Naoki's comment
- more cosmetic fixes
- reordered OPERATION enums
- removed no longer used code
- follow pmd, etc. where easily possible
