Support the initial data for the node in InterProcessReadWriteLock

Currently, locks(writeLock, readLock) in InterProcessReadWriteLock use the InetAddress for a initial data for the node, It is a little difficult to debug the lock owner as it shows only IP. If the initial data for lock node can be set, participantNodes contains the given information(hostname, id). So, it is easy to debug participantNodes.

writeLock = InterProcessReadWriteLock.writeLock();
Collection<String> nodes = writeLock.getParticipantNodes();
for (String node: nodes) {
    String nodeData = new String(client.getData().forPath(node));
}

nodeData should be the information which is given in argument.
