Add option to force sync repository
Description of problem:
Pulp now gives us the ability to force sync a repository, katello should expose that to the user. This bypasses all the normal checks that would cause pulp to skip the publish.
Refs #18558 - Add advanced sync optionsThis adds two new sync options to the sync action:
- skip_metadata_check - pulp's version of 'force_full'
- validate_contents - uses on_demand, repository download action
with verify_all_units to verify checksums and redownload corrupt
or missing packages
