  - Merge "OCI Basic Auth/Tag access"
  - OCI Basic Auth/Tag access

    In order to support the deployment of OCI images utilizing bifrost,
    we also need to explicitly support basic authentication.

    This has been extended to support inclusion of the authentication
    credentials into the pull secret string, and fallback on the deploy
    interface settings for static configuration. While this will likely
    never be perfect, it is at least a forward step to better supporting
    a variety of use cases.

    Additionally, doing some of this highlighted some extraneous guard
    rail style checks which exist elsewhere in the overall image handling
    flow. A exeception check was added to prevent tag based deployments
    from failing because the existing code structure of the guard rail
    checks cannot gain the context around basic auth.
    In part becasue the check directly uses the image_source as well,
    as opposed to any other state data which is presently available
    in deploy_utils when the image information is identified.
    That situation highlights why additional fixes are needed,
    but bug 2133885 was opened for that separately.

    Claude also helped me out with the unit tests.
