This covers everything a Flink Administrator (that is, someone with the ability to create FlinkDeployment CRs) needs to be able to create a Flink cluster. For the sake of this Epic we will exclude FlinkDeployment running in 'application mode' (i.e. this Epic covers only FlinkDeployment CR which lack a spec.job).

This includes:

• Securing the cluster (e.g. documenting the use of a NetworkPolicy)
• Docs
• Examples (including setting up Prometheus to scrape metrics)
• Testing
