When asking for the known groups a user belongs to they may belong to an internal group by way of membership in a non-internal group, such as LDAP. Cache in memory the complete list of any non-internal group UUIDs used as members of an internal group. These must get checked for membership before completing the known group data from the internal backend. Change-Id: I10aef9f185915771deb58f4f180818c08e784ea3
