SQL identity driver does't support backend filtering on membership queries

[Henry Nash]

The SQL identity driver leaves filtering on list_users_in_group and list_groups_for_user to the controller. This is probably a reasonable assumption - although the LDAP driver now does support at least filtering on list_groups_for_user (this is included in https://review.openstack.org/#/c/147612/). It would be sensible for SQL to at least match what LDAP can do (and avoid having to skip the test related to this in test_backend_sql).

Does this need a spec?

    Implement backend filtering on membership queries

    Enable filtering on list_users_in_group and list_groups_for_user in the
    SQL identity driver. The LDAP identity driver currently does not support
    filtering on the listing users for a given group, so test override was added
    to the LDAP driver.
