radi version outputting does not work

[james-nesbitt]

When trying to output the radi cli version, an error is produced:

-> % radi -v     
flag provided but not defined: -v
Usage of radi:
  -debug
        Enable verbose debugging output
  -environment string
        Activate a specific environment (default "local")

but the general radi help says that it is a valid flag:

GLOBAL OPTIONS:
   --environment value  Activate a specific environment
   --debug              Enable verbose debugging output (default: false) [$RADI_DEBUG]
   --help, -h           show help (default: false)
   --version, -v        print the version (default: false)

we have the same issue with the --help flag.

These issues occur because we have a hack in place to allow us to preprocess flags before passing them to our cli library (github.com/urfave/cli.)

The simple fix is to just add these flags to our hack, but ignore them.
