get_adapter_conf_options(include_deprecated=False) results in NoSuchOptError

[Eric Fried]

If you keystoneauth1.loading.get_adapter_conf_options with the new [1] include_deprecated kwarg set to False, you get a list of opts that excludes 'interface'.

If you then register these opts, and then attempt to keystoneauth1.loading.load_adapter_from_conf_options, you'll get "NoSuchOptError: no such option interface in group [whatever]".

This is because the loading code expects the interface opt to be present [2] [3].

    Protect against missing interface attribute

    If deprecated options aren't registered, interface will not exist,
    resulting in NoSuchOptError.

    Add safeguards around accessing the interface opt, and appropriate test
    cases.
