[APER-2504]
This is a companion to PR #32458. This updates the `notify_credentials` management command and adds an additional argument/switch (`--revoke_program_certs`).
If included, this option will be converted to a boolean and passed as a script option. Eventually, the `send_notifications` function (updated in the previously mentioned PR) will determine if we should fire a signal that checks if any program certs need to revoked.
