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).

Contributor guide

Research direction
Inspect the controller code, particularly the routing and handler setup, to understand where HEAD requests are being blocked. Look for the changes in PR #4494 and implement a handler that returns appropriate headers for HEAD requests.
