Move virtual interfaces test into misc policy actions file

Move test_list_virtual_interfaces into
test_server_misc_policy_actions_rbac.py to further increase gate
stability and decrease gate run time.

The number of calls to create_test_server() should be minimized
for RBAC testing because we don't do too much modification to the
resources that are created -- only what's necessary to trigger the
API action corresponding to the RBAC policy under test. Further,
minimizing such calls reduces the risk of spinning up too many servers
concurrently in our gates: the source of various gate failures as
limited resources lead to server faults being raised.
