An option to set additional annotations and service account names for the MongoDb cfg service

[virtyaluk]

Hello there!

I'm looking for ways to set additional pod annotations and service account names for the cfg statefulset service created by the MongoDB operator. I'm using a 3rd party mutation webhook that intercepts the pod-creating flow to insert sensitive data from the Vault secrets store in place of referenced Kubernetes secret values (basically every time it runs into a Valut-specific syntax in place of a secret value, it'd then call Vault API to retrieve a real secret value and replace original value). The webhook behavior is configured through pod annotations and the default account name. Since the cfg service is responsible (I presume) for the creation of default MongoDB users, I need the cfg service to come with Vault configuration for it to know how to talk to the Vault cluster. I couldn't find any configuration options in the helm value files. Is there any at all? If not, will it be possible to expand the configuration options to include the cfg set of options just like there is one for the rs0?

Thanks.
