Approach

What is the motivation for this PR?

1. Implement the regression test case of PSU power threshold exceeding check.
   It can be done on a per vendor/platform basis only because the way to trigger PSU power threshold exceeding varies among vendors and platforms.
2. Support parsing WARNING state in the output of show platform psustatus

How did you do it?

We implement the test as a mock test because

• It's not able to meet the conditions to trigger the PSU power to exceed its threshold in any regression test bed, (which requires 100% utilization of throughput and high power-consumption xSFP modules
• PSU power threshold exceeding checking is not supported on all testbeds. If we would like to run the test on a test bed which does not physically support it, we also need to mock it.

How did you verify/test it?

Manually test and run regression test.

Any platform specific information?

Mellanox platforms only.

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