BOOKKEEPER-748: Move fence requests out of read threads
This change is moving the fence request out of current read threads and
using callback to trigger scheduling read entry and also it refactors the
ReadEntryProcessV3 to support long poll in the subsequent requests.
Major changes:
- change fence request to use SettableFuture
- refactor ReadEntryProcessV3: to support run fence request in callback and
support long poll (in subsequent requests)
- fix stats issue: requests stats measure the latency from bookie receives
the request until it sends the response.
- remove "public static final" for state fields. it is not needed for
variables in Interface.
