[i-g-t 1/2] tests/kms_feature_discovery: Add basic sanity test

[Sharma, Swati2]

As discussed offline, we need to differentiate between server and client 
platforms for this test. In both the cases, this test will pass.
Either we skip this test for server platform or we need to think of 
something else.
