Update nr.nc to have dedicated list of arguments

[gcasella]

Continuation of our discussion on Slack;

When using the following nr.nc rpc command

salt 'nrp02' nr.nc rpc rpc="salt://templates/my_rpc.xml" FO='[{"hostname": "192.168.2.2"}]'

This would provide an invalid response, the needed command to be run was providing the full string of my_rpc.xml in the cli.

salt 'nrp02' nr.nc rpc rpc="FILTER_NAME" FO='[{"hostname": "192.168.2.2"}]'

Adding the render='["rpc"]' argument at the end of the first command was successful
Adding screenshot from slack for reference;
