[HADOOP-8337] Clarify the usage documentation for fetchdt

Description

The -webservice URL option in fetchdt is very fragile. In particular, it must be precisely in the form of the http://<nn>:<port> and NOT include the trailing slash. Furthermore, after HDFS-2617 the <nn> must be a lowercase hostname and not an IP address.

I propose at least documenting all of the restrictions...
