Description

This is the followup of CASSANDRA-6285, to decide what we want to do regarding thrift servers moving forward. My reading of CASSANDRA-6285 suggests that the possible options includes:

1. bring back the old HSHA implementation from 1.2 as "hsha" and make the disruptor implementation be "disruptor_hsha".
2. use the new TThreadedSelectorServer from thrift as "hsha", making the disruptor implementation "disruptor_hsha" as above
3. just wait for Pavel to fix the disruptor implementation for off-heap buffers to switch back to that, keeping on-heap buffer until then.
4. keep on-heap buffer for the disruptor implementation and do nothing particular.

I could be missing some options and we can probably do some mix of those. I don't have a particular opinion to offer on the matter.
