Add ignoreNotFound flag to KubectlDelete.java

[awesominat]

This PR fixes #2876, an issue where attempting to delete a resource that doesn't exist throws an exception and causes the user to catch the exception.

Now, by setting the ignoreNotFound flag, exceptions don't have to be explicitly caught.
