Description

Current storage protocol (everything beneath o.a.c.net) currently uses Java blocking I/O. I.e. InboundTcpConnection and OutboundTcpConnection use a dedicated Java thread per connection.

Using NIO would reduce the number of threads as many threads can become a problem in bigger clusters.

Migrating the code to Netty seems to be a prerequisite for thread-per-core model.

The intention of this ticket is not to change the protocol itself as CASSANDRA-8971 would do.
