Data Processing: Allowing for HDFS data sources without hdfs://

Now that HDFS data sources can be either full URLs
or paths relative to the cluster itself, it is no
longer desirable to force "hdfs://" at the start
of hdfs data sources.
* No longer force the prefix on the create form
* For swift, we now check to see that the location
  starts with swift://, if it doesn't we add it
