Subject: [SERVER] Support finer control over replication when a proxy connects
 to a proxy

Introduce new flag in "select image" message to tell the uplink server
whether we have background replication enabled or not. Also reject
a connecting proxy if the connecting proxy uses BGR but we don't, as this
would basically force the image to be replicated locally too.
