  - Merge "OCI: Add an option to fallback to HTTP"
  - OCI: Add an option to fallback to HTTP

    While working on trying to get OCI support in CI, I realized that the
    default pattern setup with Bifrost was to setup a registry *without*
    HTTPS.

    This is different from the common practice and expectation of operational
    OCI registries always utilizing HTTPS as the underlying transport mechanism.

    The net result is an idea of offering the ability to "fall back" to HTTP
    automatically, and make it a configuration option which needs to be
    chosen by an operator.

    The code pattern is such that the invocation of the client code paths
    automatically identify the SSLError, and then attempt to fallback
    to HTTP, while also saving the fallback on the class instance so the
    additional URL generation calls for the underlying HTTP(S) client
    gets an appropriate URL.

    By default, this new option is disabled.

    Claude helped with the tests, which was nice of it.
