OSASINFRA-2999 - ControlPlaneLoadBalancer support

Creates a new interface to be able to choose which load-balancer to deploy in the Control Plane. For on-prem, this will allow to not deploy Keepalived/HAproxy but use BGP (with FRR) in MCO. This API is required so: * we expose load-balancer options from the install-config * we add these options in the PlatformSpec, so it can be used in the cluster, and changed on day 2. enhancement: openshift/enhancements#1281 feature: OSASINFRA-2999 Co-authored-by: Matthew Booth <mbooth@redhat.com> Co-authored-by: Pierre Prinetti <pierreprinetti@redhat.com> Co-authored-by: Emilien Macchi <emilien@redhat.com>
