Some AWS installs are failing to bootstrap due to an issue where CAPA may fail to create load balancer resources, but still declare that infrastructure is ready (see upstream issue for more details).

In these cases, load balancers are failing to be created due to either rate limiting:

time="2024-05-25T21:43:07Z" level=debug msg="E0525 21:43:07.975223     356 awscluster_controller.go:280] \"failed to reconcile load balancer\" err=<"
time="2024-05-25T21:43:07Z" level=debug msg="\t[failed to modify target group attribute: Throttling: Rate exceeded" 

or in some cases another error:

time="2024-06-01T06:43:58Z" level=debug msg="E0601 06:43:58.902534     356 awscluster_controller.go:280] \"failed to reconcile load balancer\" err=<"
time="2024-06-01T06:43:58Z" level=debug msg="\t[failed to apply security groups to load balancer \"ci-op-jnqi01di-5feef-92njc-int\": ValidationError: A load balancer ARN must be specified"
time="2024-06-01T06:43:58Z" level=debug msg="\t\tstatus code: 400, request id: 77446593-03d2-40e9-93c0-101590d150c6, failed to create target group for load balancer: DuplicateTargetGroupName: A target group with the same name 'apiserver-target-1717224237' exists, but with different settings" 

We have an upstream PR in progress to retry the reconcile logic for load balancers.
