cancelling running/in flight BuildRun

[gabemontero]

openshift build v1 allows for cancelling in progress builds via the CLI and REST

tekton cli can also cancel in progress taskruns and pipelineruns

build v2 should tie in a cancel function (assuming it already plans on a start build function) to oc

and where possible, if it makes sense to vendor in tkn code into oc to facilitate things, by all means

[adambkaplan]

This isn't a minimum viable feature, but worth pursuing in the long run. Since we use Tekton TaskRun objects under the covers, it's possible to indirectly cancel a BuildRun by cancelling the underlying TaksRun via the tkn command line.

Yes, Tekton supports it natively.

But it should also need to server side implementation, like the introduction on Tekton side:
https://github.com/tektoncd/pipeline/blob/master/docs/taskruns.md#cancelling-a-taskrun

spec:
  # […]
  status: "TaskRunCancelled"

We should be able to allow add a status like abouve in buildrun to cancel a buildrun OR we may have a logic in our controller to add the taskrun status TaskRunCancelled for the buildrun's taskrun
