Bank-Vaults Vault helm operator

A Kubernetes Operator based on the Operator SDK (Helm version) to configure official banzaicloud/bank-vaults Vault operator helm chart, so it can be installed via OLM without having to do any change on current Helm Charts.

The usual Helm Chart file values.yaml, like:

image:
  bankVaultsRepository: ghcr.io/banzaicloud/bank-vaults
  repository: ghcr.io/banzaicloud/vault-operator
resources:
  requests:
    cpu: 100m
    memory: 200Mi
  limits:
    cpu: 100m
    memory: 400Mi

Need to be encapsulated into a new custom resource called OperatorConfig:

apiVersion: operator.vault.banzaicloud.com/v1alpha1
kind: OperatorConfig
metadata:
  name: cluster
spec:
  image:
    bankVaultsRepository: ghcr.io/banzaicloud/bank-vaults
    repository: ghcr.io/banzaicloud/vault-operator
  resources:
    requests:
      cpu: 100m
      memory: 200Mi
    limits:
      cpu: 100m
      memory: 400Mi

So the operator will create all helm chart resources, using the custom resource name as a prefix for all resources names.
