canonical-certification-server has a lot of unnecessary (possibly) dependencies pulled in.

the ones marked as unnecessary are guesses for now, we'll need to sort them out over time and decide what really needs to go or stay.

canonical-certification-server depends on plainbox-provider-certification-server, which in turn depends on plainbox-provider-checkbox.

p-p-c-s (too lazy to fully type) will install the following:
Recommends: apache2,
            bind9,
            cpu-checker,
            cups,
            dnsutils,
            iperf,
            ipmitool,
            libapache2-mod-php5,
            mysql-server,
            php5-mysql,
            qemu-kvm,
            qemu-utils,
            samba,
            ssh,
            tomcat6,
            winbind

While plainbox-provider-checkbox will install some of those client-related dependencies:
Recommends: gir1.2-gst-plugins-base-1.0,
            gir1.2-gstreamer-1.0,
            gstreamer1.0-plugins-good,
            gstreamer1.0-pulseaudio,
            libgstreamer1.0-0,
            pm-utils,
            python3-apt,
            python3-dbus,
            python3-gi

We do have specific tests for cups, samba, tomcat and the entire lamp stack (look at jobs/server-services.txt.in). That's the reason for those server dependencies. We can remove them and only test if the user explicitly installed the dependencies by himself. Doing that, I fear we'll get the opposite problem, with people complaining that checkbox doesn't install those dependencies.

As for the gstreamer dependencies, I can look into moving those to another package, although none of the existing ones seems like a good fit. It would require a bit more planning. They're mainly there for the video and audio tests, which are only relevant for desktop testing.
