Retrieves information from Flume master HTTP pages.
Information gathered:
* Flume version
* Flume server id
* Zookeeper/Hbase master servers present in configured flows
* Java information
* OS information
* various other local configurations.
If this script is run wth -v, it will output lots more info.
Use the <code>newtargets</code> script argument to add discovered hosts to the
Namp scan queue.
