Register deprecated opts with Adapter.get_conf_options

[Eric Fried]

keystoneauth1.loading.session.Session.get_conf_options has a deprecated_opts kwarg to register deprecated options such that, if you're replacing an existing (usually non-ksa) option with one from ksa Session, you can associate a DeprecatedOpt with the ksa Session opt.

keystoneauth1.loading.adapter.Adapter.get_conf_options doesn't have this facility.

There is demand for this function in the efforts of running endpoint/version discovery consistently through ksa. For example, the nova work for blueprint use-service-catalog-for-endpoints needs to be able to deprecate [ironic]api_endpoint in favor of Adapter's endpoint_override option.

    Adapter.get_conf_options(deprecated_opts)

    Support a deprecated_opts dict kwarg to
    keystoneauth1.loading.adapter.Adapter.get_conf_options that behaves just
    like the one for keystoneauth1.loading.session.Session.get_conf_options

    Ditto register_conf_options.
