Description

This patch allows the operators to disable older protocol versions on demand. To use it, you can set native_transport_allow_older_protocols to false or use nodetool disableolderprotocolversions. Cassandra will reject requests from client coming in on any version except the current version. This will help operators selectively reject connections from clients that do not support the latest protoocol.
