SSL Certificates: Show if cert is in use on host (and if host is disabled or enabled)

[badkeyy]

Issue

Fixes #4221

Description:

This PR enhances the SSL Certificates list by adding a Status indicator, indicating if a SSL Certificate is in use on a proxy host or not. If it is in use the domain names for which it is in use on are shown in the dropdown menu of the list item.

Screenshots

Sorry for setting the status of this PR back to Draft but I noticed that I forgot to implement this feature for dead_hosts and redirection_hosts
