CA bundles for hosted cluster monitoring not created

alertmanager-trusted-ca-bundle, prometheus-trusted-ca-bundle, telemeter-trusted-ca-bundle, thanos-querier-trusted-ca-bundle are empty on the hosted cluster. This results in CMO not creating the prometheus CR, resulting in no prometheus pods. 

This issue prevents us from monitoring the hosted cluster.
