cassandra thrift version 19.10.0->19.19.0
* introduce ConnectionError for distinguishing pooling errors that should get reported back to the user and errors that the driver should try to address.
* Connection uses a timeout to handle instances where a query never finishes (this has been observed with some transport errors).
* ConnectionInPool extends Connection and keeps track of connection state and health.
* PooledConnection2 is API compatible with PooledConnection (will replace it in next commit).
build thrift connection during connect.
* add cassandra-env.sh so that JMX gets started (port 7199)
* dial log level down to debug.
