Remove openshift-enterprise-yum-validator.

openshift-enterprise-yum-validator is a tool that performs a pre-flight
check. The installer performs this test and in some cases the pkg is
not availble until the installer is run and registration is done.
The validator version param is unnecessary.

Delay creating mongo replica set until other broker hosts available

MongoDB requires all members of the replica set be up when
initiating the replica set. This change delays the creation of
the rs until the other brokers have had a chance to reboot. The
openshift.sh script is used by setting the CONF_ACTIONS env var.
