We don't have glance in the undercloud by default. Though we
currently fall back to upload locally if glance is not
available. Let's make local upload the default and deprecate
image upload to glance. This would help avoid looking glance
endpoint in the catalog, which would not be available in the
noauth use-case.
We'll drop GlanceClientAdapter when we remove option to enable
glance from the undercloud.
