action #15132: [epic] Better structure of test plans in main.pm
[functional][y] Use new yaml structure for test suites to define different schedules for different env
|Category:||Enhancement to existing tests|
|Target version:||QA - future|
As of now, when we have even small differences in the schedule, we have to clone the test suite (like we did for RAID tests). When #44360 is resolved, we will be able to reuse same test suite template and provide different settings on medium-machine layer making it simpler to manage for the different backends.
