Checkmk Werk 14074: Agent controller: Try to query port both via <tt>http</tt> and <tt>https</tt>

ID: 14074 Title: Agent controller: Try to query port both via <tt>http</tt> and <tt>https</tt> Component: agents Level: 1 Class: New feature Version: 2.2.0i1 When registering at a site, the agent controller (<tt>cmk-agent-ctl</tt>) needs to know the port at which the site is reachable. If not explicitly passed via the command line, the controller tries to query this port from the REST API of the site. Up to now, the controller only attempted to contact the REST API via <tt>http</tt>. Now, the controller tries both <tt>http</tt> and <tt>https</tt> and only fails if neither of the two suceeded.
