Issue XD-1745: Support for hadoop name node HA configuration
Hadoop supports namenode HA with two name nodes running, one being active and other in standby. If the active name node fails the standby name node has all the data readily available and can start serving requests. In this configuration name node url is no longer a host:port url but a logical name that translates to any active name node at runtime. This is to ensure spring xd stream can handle a name node failure, for instance when writing a hdfs sink, seamlessly
