Subject: [PATCH] Reattach monitors

Teach vdagent to attach monitors. A monitor needs to be enabled before
we can set the custom resolution. Fortunately, the client doesn't seem
to have time to catch that, so things are smooth.

This is require to allow the virt-viewer display menu to work properly
and enable extra monitors: https://bugzilla.redhat.com/show_bug.cgi?id=919530
