Gleb Natapov 0d0c05a569 lwt: allow only one paxos instance to run for each key simultaneously ...

This will prevent contention in case of parallel updates of the same row
by the same coordinator. The patch does it by introducing a new per key
lock map and taking it before running PAXOS protocol (either for write
of for read).
