ci: add capability to run specific e2e tests

The current e2e test runs will trigger all 3 types of
tests which takes a lot of time to complete. If the
patch impacta only a single type, then having an option
to trigger only that particular e2e test can save
considerable amount of time based on the test type.

This can also help in reducing the time in testing when
a patch failed on a particular e2e test type and triggering
only that e2e with the fix for the failure or re-trigger
only that test again to check for false positives.
