-----------------------------------------------------------------------

Some updates: added to ccm the ability to send a byteman rule when restarting a 
node (https://github.com/ostefano/ccm/tree/startup_byteman). Originally it was 
only possible to submit a rule _after_ the node started, which made reproducing 
this race quite impossible.

With that I could finally reproduce the bug. Here you can my branch with a new 
DTEST exercising the bug: 
https://github.com/ostefano/cassandra-dtest/tree/CASSANDRA-13043

Attached you can find a patch fixing the bug by removing nodes that are not RPC 
ready from a leader election. Also, I fixed the corner case where the CL 
required is local and the current DC does not have available nodes.

Here you can find the commit:
