Have nl01.o.o manage min-ready of labels

Due to how multiple nodepool-launchers work today, it is possible to
have greater then min-ready of a label. To avoid this, nl01.o.o will
now be the only launcher to send min-ready requests to zookeeper.

Ideally, nodepool will be updated to support shared configuration in
the future.
