Approach
What is the motivation for this PR?
The existing telemetry tests used rand_one_dut_hostname which would run on a randomly selected DUT in a multi-dut testbed like T2 chassis. In T2 chassis, this random dut could be a supervisor card, and in this scenario, some of the telemetry tests would fail because of dependency on Ethernet0 frontpanel port.
How did you do it?
How did you verify/test it?
Tested on T2 chassis and confirmed that the tests pass and run against linecard and supervisor card.
Any platform specific information?
Supported testbed topology if it's a new test case?
