Description of PR

Summary: Goal of this PR is to set correct topology marker for test_vrf, for some reason topology is marked as any, although it is not correct if to compare with vrf test_plan which points that vrf test_cases should run on t0 topo. When run on t1, all tests cases fail on setup due to "KeyError: 'VLAN_MEMBER'".

ERROR    test_vrf:test_vrf.py:381 Exception raised in setup: KeyError('VLAN_MEMBER',)
