enhance(executor tests): Add kubernetes runtime test cases for Build …

…tests (#438)

* test(executor): add kubernetes runtime to CreateBuild test

* test: Use kubernetes runtime in executor build tests

The kubernetes Mock does not support some of the failure modes simulated
by the docker Mock. So, those test cases are commented out with a FIXME.

* cleanup commented blocks

* test(executor): add remaining StreamBuild k8s test cases
