management: enterprise users must acknowledge use of beta software

Adds a new role variable, openshift_management_install_beta. This
variable defaults to false. The value of this variable is checked
during the validation phase for enterprise deployment types.

* If true, the install will not continue.

* If false, The user is presented with an informative message letting
  them know this is beta software and there is low/no support at this
  time. The installation will abort and instruct the user how to
  continue.

 old application or database deployments before attempting to
 initialize a new deployment.
 
+Failure to erase old PostgreSQL data can result in cascading
+errors. The postgres pod may enter a `crashloopbackoff` state. This
+will block the management pod from ever starting. The cause of the
+`crashloopbackoff` is due to incorrect file permissions on the
+database NFS export created during a previous deployment.
+
+To continue, erase all data from the postgres export and delete the
+pod (**not** the deployer pod). For example, if you have pods like
+such:
+
+```
+# oc get pods
+NAME                 READY     STATUS             RESTARTS   AGE
+httpd-1-cx7fk        1/1       Running            1          21h

+postgresql-1-6w2t4   0/1       CrashLoopBackOff   1          21h
+```
+
+Then you would:
+
+1. Erase the data from the database NFS export
+2. `oc delete postgresql-1-6w2t4`
+
+The postgres deployer pod will try to scale up a new postgres pod to
+replace the one you deleted. Once the postgres pod is running the
+manageiq pod will stop blocking and begin application initialization.
