Use tenant_network if any in testcases after microversion v2.37
Now in testcases after microversion v2.37, if networks isn't passed
to create_test_server explicitly, no tenant_network will be retrieved
automatically, so they will always use networks='none'.
This is to use tenant_network if any be can found in testcases
after microversion v2.37 if networks='none' is not explicitly specified.
(if networks='none' is explictly specified, we should use it
prior to using tenant_network)
