document --ui_validate_io switch

[brianwcook]

--ui_validate_io was asked to be used to verify data for operatorhub.io, but it isn't documented in readme or in the --help output.

@brianwcook, is this an issue with the verify or the push subcommand? Should both have this option?

With the version from master I see this:

$ operator-courier verify -h
usage: operator-courier [-h] [--ui_validate_io]
                        [--validation-output VALIDATION_OUTPUT]
                        source_dir

Build and verify an operator bundle to test

positional arguments:
  source_dir            Path of your directory of yaml files to bundle. Either
                        set this or use the files argument for bundle data.

optional arguments:
  -h, --help            show this help message and exit
  --ui_validate_io      Validate bundle for operatorhub.io UI. To visually
                        confirm that your operator will be displayed

                        and paste your operator CSV.
  --validation-output VALIDATION_OUTPUT
                        A file to write validation warnings and errors toin
                        JSON format

and

$ operator-courier push -h

                        source_dir namespace repository release token

@brianwcook Could you elaborate on this a little bit? What sort of documentation are you looking for? Docs on how to invoke this flag? Or docs on how to use the output? Both?
