Empirically, Cassandra does not appear to send
TopologyChangeType.REMOVED_NODE when a node in the ring
crashes hard and is eventually replaced, even though the
bad node is removed from the system tables. This results in
the driver holding on to that node until a restart.
The 3.x driver refreshes the entire node list when a node is
added, so when a new node comes up to replace the crashed
node, the crashed node is removed from the driver's state.
With this change we port that behavior to the 4.x driver and
refresh the entire node list when a new node is added.
This also fixes JAVA-3002.
