HostPrefix not configurable but CIDR is

[mihaime]

Hi guys,

I was trying to do a small lab setup and set the POD network to /24.
Then upon deploying I noticed that the Openshift playbooks complained about HostPrefix /23.
Investigating more showed that here:
acc-provision/provision/acc_provision/templates/cluster-network-03-config.yaml
we have cidr configurable (set from the acc-provision script) while the HostPrefix is static and always /23.
I'm thinking that it should also be configurable as Redhat in its documentation does allow it for its native Openshift deployment.
Changing it otherwise later is a cumbersome process (unpacking the manifests.tar.gz, manual change, repacking the archive).
