Rackspace is requiring multi-factor authentication for all users
beginning 2024-03-26. Enabling MFA on our accounts will immediately
render password-based authentication inoperable for the API. In
preparation for this switch, add new cloud entries for the provider
which authenticate by API key so that we can test and move more
smoothly between the two while we work out any unanticipated kinks.
