Description

The change in this PR https://github.com/apache/incubator-openwhisk/pull/4494/files disabled automatic HEAD responses from the controller. So we need an explicit handler to restore this behavior. This has affected at least one downstream project (https://github.com/apache/incubator-openwhisk-devtools/pull/270).
