see if cluster meets IBM Cloud Pak for Data pre-req requirements

[tseelbach]

This pre-req checking tool seems like a good way to confirm the cluster nodes meet requirements for OpenShift installation and that OpenShift meets Cloud Pak requirements https://github.com/IBM-ICP4D/Install_Precheck_CPD_v3

Would be good if we can leverage it. To use it, the VCD terraform based install would probably need to pause between node creation and OCP installation

we should be able to automate this in the terraform. It could run the script on the bastion and fail the install if the pre-reqs aren't met or continue the terraform if pre-reqs are met. We also played around with this other tool that could run https://github.ibm.com/jerome-tarte/cp_checker does similar thing, might not be as comprehensive but doesn't require installation of software on RHCOS nodes. The pre-checks are configurable so you could just create a separate config file rather than a separate project for each CP.
