To help with code readability, include daemons from `pkg/daemon/ceph` as `<dmn>daemon "github.com/rook/rook/pkg/daemon/ceph/<dmn>`. This will make it easier to understand code lines without needing to scroll up to check the includes, as there are mon/mds/mgr/osd/rgw packages for daemons as well as operator and cmd.
