[FAB-3724] /examples/cluster: Ensure CA starts first

We want the IP address assigned to CA to be consistent.
Right now, the CA and ORDERER race and thus we can't
be sure which IP they will each be assigned.  This patch
forces the order and thus makes the assignment much more
deterministic.

Fixes FAB-3724
