Description of PR

Summary:
Fixes # (issue)
This PR fixes issue #14603 introduced as part of #14552.

With the PR #14552 changes, for modular chassis a new prolonged wait of minimum 15 minutes is added for DUT reboot test flow.

This introduced new issues with BGP test suites/cases which are dependent on reboot flow. For example, T2 chassis test cases under test suites like bgp 'test_startup_tsa_tsb_service.py' and bgp 'test_reliable_tsa.py' are failing.

Approach

What is the motivation for this PR?

• Test cases under BGP test suites like 'test_startup_tsa_tsb_service.py' and 'test_reliable_tsa.py' are failing saying DUT is not in the expected functional state after reboot.
• This is because for modular chassis, a new prolonged wait of minimum 15 minutes is added for DUT reboot test flow.

How did you do it?

• Exclude BGP test cases from the prolonged new wait and timeout time for modular chassis.

How did you verify/test it?

• Ran all the BGP test suites and make sure they are working as expected.

Any platform specific information?

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