Deprecation Notice

The workflow-controller-configmap introduces a new config field, executor, which is a container
spec and provides controls over the executor sidecar container (i.e. init/wait). The fields
executorImage, executorResources, and executorImagePullPolicy are deprecated and will be
removed in a future release.
