OpenLiteSpeed packages without the required dependency of php

OpenLiteSpeed should be able to be installed from the repo without forcing the user to install php7.3 (lsphp73) ,ie. what if one wants to use php74 or does not want php at all (ie running lua or python)?

Start by inspecting the OpenLiteSpeed package dependency metadata and reproducing the documented apt installation commands on Ubuntu Bionic. Trace why lsphp73, lsphp73-json, lsphp73-mysql, and lsphp73-imap are mandatory, then verify that installation can use another PHP version or no PHP runtime when appropriate.
