LMAX Disruptor backed Thrift Server implementation.

This server is half-sync/half-async and uses separate invocation executor.

On 4 node cluster with SSDs and RF=3 Cassandra (trunk branch, stress -n 3000000, QUORUM read/write) shows around 3x (!) improvement in read and 2x (!) improvement in write speed as well as significant latency improvements over THsHaServer and about 1.5x read/write throughput and 2x latency improvement over TThreadedSelectorServer.
