    [stable only] Add warning about rbd_keyring_conf

    This adds a warning message to the driver documentation page to make
    sure it is visible that this config option should not be used due to
    security concerns. We can't backport the deprecation of the config
    option, but we can backport this doc warning to help prevent this option
    from being used.

    Also includes part of a squash for the release note from:
    Deprecate rbd_keyring_conf option
