Register this connection to receive some type of events. The body of the
message is a [string list] representing the event types to register to. See
section 4.2.6 for the list of valid event types.
The response to a REGISTER message will be a READY message.
Please note that if a client driver maintains multiple connections to a
Cassandra node and/or connections to multiple nodes, it is advised to
dedicate a handful of connections to receive events, but to *not* register
for events on all connections, as this would only result in receiving
multiple times the same event messages, wasting bandwidth.
