Add HEAD request method for HTTP Request Action

Hi @bdunphy

I added code to dev version, please try use dev version.

I will check and release new version later.

Regards.

@zipme_hkt - I have tested using the dev version. Tested with HEAD, GET, and POST for the request method and no issues whatsoever. Thank you for the fast turnaround here.

@zipme_hkt - checking in to see if you need any further testing or anything else from me. Thanks!
