Federated users with Admin role in a domain cannot see or manage project quotas

[Diko Parvanov]

We have federated domain and users added via saml melon. Adding a federated user either the Admin or Admin --inherited role to a domain doesn't show the option to modify quotas, however visiting manually the URL https://horizon/identity/<PRPOJECT_UUID>/update_quotas/ I can NOT see the current ones (blank input fields) but I can populate them and on Save they all modify (verified by the openstack cli with admin user)

This looks like an UI bug for federated users, as this does not happen with native keystone users.
