Approach

What is the motivation for this PR?

In a SONiC chassis, we have 'supervisor' cards (control cards) that are not running 'bgp' dockers.

If we use the multi-DUT approach, we are including the 'supervisor' card as well in the list of DUTs. Thus, test_bgp_facts gets run on 'supervisor' card as well.

We need to skip the test when duthost is a 'supervisor' card.

How did you do it?

A card is identified as a 'supervisor' card, if it has a 'type' field in its host vars in the ansible inventory that is set to 'supervisor'.
We use this check to figure out if the test is to be skipped.

How did you verify/test it?

Ran test_bgp_facts against a SONiC chassis with two linecards (board1, board2) and a supervisor card (supervisor1). Results summary below:

============================================================================== short test summary info ==============================================================================
PASSED ../tests/bgp/test_bgp_fact.py::test_bgp_facts[board1-None]
PASSED ../tests/bgp/test_bgp_fact.py::test_bgp_facts[board2-None]
SKIPPED [1] /data/tests/bgp/test_bgp_fact.py:17: bgp_facts not valid on supervisor card 'supervisor1'
=================================================================== 2 passed, 1 skipped in 83.83 seconds ===================================================================

Any platform specific information?

Supported testbed topology if it's a new test case?
