It's very common for users to want to use load balancer features that are available to OpenShift via service annotations. Examples of which are setting a static ip [1], or enabling load balancer logging for compliance [2] or creating an allow-list of IPs that can access the LB [3].

as ALBO support comes in to OpenShift these annotations will allow for some fairly complicated logic to do things like enable WAF / CloudFront.

Proposal is that the operator would add a field in its CRDs for `serviceAnnotations: {}` that would be passed through to the service that is created for the ingress controller.
