nodetool: parse and forward -h|--host to nodetool

Our launcher script (bin/nodetool) currently silently ignores the host
parameter and nodetool will use the default value (127.0.0.1). This
patch parses and forwards the host parameter to nodetool, so that it is
possible to start JMX on other ips than 127.0.0.1.
