Prometheus, PrometheusAgent

What is missing? Please describe.

prometheus/prometheus#16421 made the client_id field optional. The field is currently required on the CRDs so it needs to be made optional. Having said that the operator should ensure that the deployed Prometheus version supports the field being unspecified.

Describe alternatives you've considered.
