[POSSIBLE BUG] nr.file read and base_url parameter not accepted via cli

[bodleytunes]

it seems that using:
salt nrp1 nr.file read filegroup=backup base_url="/var/salt-nornir/nrp1/files/kmx/backups/tf"

seem to get the error got multiple values for keyword argument 'base_url'

While the above base_url will work in nornir salt via Python directly.

this was added in 0.20.2 release
