This is amazing! Looks very good to me. I left several suggestions and questions.
Can't wait to get rid of this flakiness, thanks a bunch @GuptaManan100 🚀

By the way, @GuptaManan100, do you have an approximate idea of how flaky the tests are, (if they are), with this new configuration?

one suggestion, the rest LGTM.
We can merge once all feedback is addressed.

By the way, @GuptaManan100, do you have an approximate idea of how flaky the tests are, (if they are), with this new configuration?

Yes, @frouioui The unit tests fail about once in 3 runs and vreplication tests fail once in 4 runs. It is less flakier than GitHub runners and faster too. The major motivation of this however, is to be able to look at the logs of the vtdataroot directory and fix the flakiness. With this change we will be able to easily move a test to the self-hosted runners if it is flaky and fix the issue
