Handle robot_unavailable errors when creating load balancers or adding targets to a load balancer #1134

/kind feature

Describe the solution you'd like According to the Hetzner documentation there is a possibility for the error robot_unavailable for both the operations https://docs.hetzner.cloud/#load-balancers-create-a-load-balancer and https://docs.hetzner.cloud/#load-balancer-actions-add-target.

We should implement a handling of this error code and wait for some time before we try this operation again. In this way, we prevent the controller from calling the API again and again.

We should include a condition (respectively a reason for a condition) that tracks this temporary problem for users.

I guess this issue is still valid, and we should handle these cases.
