cv-rvr: Fix up rvr test

And tweak a few others to not have default args so that
if nothing is entered, defaults (or raw config lines/files
content is used if it exists.)

 Note:

     --raw_line 'line contents' will add any setting to the test config.  This is
         useful way to support any options not specifically enabled by the
         command options.
     --set modifications will be applied after the other config has happened,
         so it can be used to override any other config.
