raft-pebbledb

This implementation uses the maintained version of PebbleDB. This is the primary version of raft-pebbledb and should be used whenever possible.

There is no breaking API change to the library. However, there is the potential for disk format incompatibilities so it was decided to be conservative and making it a separate import path.

Cautions:

1. raft-pebbledb write kv datas, use pebble.Sync WriteOptions which synchronize to disk.
2. if use pebble.NoSync WriteOptions which do not synchronize to disk, maybe lost data when the program crashed suddenly.
3. if we call Flush() before exit process for flush datas to disk, use pebble.NoSync WriteOptions will not be lost datas.
