Make PostgresContainerName configurable

[egerkke]

Hi Ladies and Gents,

Please, answer some short questions which should help us to understand your problem / question better?

• Which image of the operator are you using? ghcr.io/zalando/postgres-operator:v1.10.0
• Where do you run it - cloud or metal? Kubernetes or OpenShift? K8s
• Are you running Postgres Operator in production? yes
• Type of issue? feature request

Currently PostgresContainerName is hard-coded with name postgres : kubernetes.go

Would it be possible to make it configurable?

Many thanks in advance!
