The cancellation of taskruns is now done through the entrypoint binary through a new flag called 'stop_on_cancel'. This removes the need for deleting the pods to cancel a taskrun, allowing examination of the logs on the pods from cancelled taskruns. Part of work on issue #3238
there are some codes carry over from #4618

@chengjoey thank you for these contributions, and for the patience with the reviews

this pull request generally looks good to me, one ask is that you improve the code coverage to at least maintain the current coverage e.g. add a test case for setting the feature flag to something invalid
