Description of problem:

For all currently supported versions, we need to include a clear statement in our docs about what load balancers are supported.

• Default ELB type for the router on AWS
• CLB on self managed
• NLB on ROSA

• All 3 types (CLB, NLB, and ALB) are supported on OpenShift
• ALB is intended to be used directly in front of an application, not in front of the router.
• Using ALBs requires using the addon AWS Load Balancer Operator and is not supported for all AWS regions and OpenShift profiles.
