Check Cluster CPU/Memory Resources in Bootstrap

[strangiato]

When deploying a cluster with the bootstrap script it is not uncommon to not have enough resources in the nodes to successfully deploy everything.

It would be great if the bootstrap script did a check of the available CPU and Memory and made sure that there was more than a set minimum of both of those resources. If it doesn't it may give you a warning and provide you the option to continue (allowing you to correct the issue by spinning up additional nodes if you wish to).

An initial estimate is about 20 CPUs and 50 GiB required.

Great idea, while installing on a default AWS OpenShift cluster I get the following issues in ArgoCD:

By default, it looks like no dedicated worker nodes are scaled up on the demo.redhat.com instance, meaning that they hyper-converged worker/control plane is running out of availability during provisioning
