Description of PR
Summary:
Changes to test TSA/B functionality from the supervisor of T2 chassis
Type of change
Back port request
Approach
What is the motivation for this PR?
sonic-net/sonic-buildimage#14691 added support for TSA/B to be invoked from supervisor. New test cases are being added to test this feature.
How did you do it?
Add test cases to run TSA, TSB from supervisor and verify that each linecard's traffic shift state is updated. Also added a test case to save TSA state from the supervisor and perform config reload on all linecards to ensure the 'maintenance' state is persisted
How did you verify/test it?
Loaded image with sonic-net/sonic-buildimage#14691 and sonic-net/sonic-utilities#2850 and ran the test cases
Any platform specific information?
Supported testbed topology if it's a new test case?
