As a fix for the issue sonic-net/sonic-buildimage#21586, TSA-TSB service is invoked upon swss bring up(sonic-net/sonic-buildimage#21587). This affects config_reload behavior, where after config reload the tsa-tsb service will be restarted, and the device will be in TSA state till timer expires. Adjusting the testcase to explicitly execute TSB for the DUT to be ready for next testcase, #### How did you do it? Enhanced the config_reload api to optionally take exec_tsb parameter. For startup-TSA-TSB and reliable TSA-TSB testcases, pass this flag to True to explicitly execute TSB on the device after config reload. #### How did you verify/test it? Ran the tests on t2 #### Any platform specific information? NA #### Supported testbed topology if it's a new test case? NA ### Documentation <!-- (If it's a new feature, new test case) Did you update documentation/Wiki relevant to your implementation? Link to the wiki page? -->
