dbus: Make the P2P peer's properties accessible separately

Browse source 
Since there is the method org.freedesktop.DBus.Properties.GetAll that
returns all properties from a specific interface, it makes more sense to
separate the properties to make it possible to get only a single
property using the method org.freedesktop.DBus.Properties.Get as well.
