Add support for Heimdal Agent
Add official support to Heimdal Agent (https://heimdalsecurity.com/) for Plesk on Linux servers, including ARM architecture servers.
It seems that Heimdal Agent is a client component of their offer that collects data from a server or interacts with the server. Nothing speaks against installing that on a Plesk maintained server. "Support for Heimdal Agent" probably means that it can be installed as an extension or from a software catalog like APS catalog?
