A `cockpit doctor` style command that extra plugins like cockpit machines can extend.

I've found that Cockpit Machines is really unreliable on Debian and it's nothing really to do with Cockpit - it's things like dbus settings that break Cockpit.

eg, having to add this to make it reliable on my Debian Trixie install:

  <?xml version="1.0" encoding="UTF-8"?>
  <!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-BUS Bus Configuration 1.0//EN" "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd">
  <busconfig>
    <limit name="max_match_rules_per_connection">4096</limit>
  </busconfig>

It would be fantastic if Cockpit could spot known issues like this and warn the user/administrator.
