Existing PVC can slip into as the storage for operator

PVC created manually (any accessModes) by user can be slip into the Operator.

Things to notice here:

• WFWIP-186 StorageSpec is intended to be mounted in ReadWriteOnce mode
• foo: bar should never pass the validation as it is not a valid storage configuration

reproduce

• create PVC, use the ${OPERATOR_NAME}-volume-${OPERATOR_NAME}-0 name - the PVC would be in normal circumstances created by the operator

  apiVersion: v1
  kind: PersistentVolumeClaim
  metadata:
    name: quickstart-volume-quickstart-0
  spec:
    accessModes:
    - ReadWriteOnce
    - ReadOnlyMany
    - ReadWriteMany
    resources:
      requests:
        storage: 1Mi
    volumeMode: Filesystem
    volumeName: pv0022
  

• deploy the project

  apiVersion: wildfly.org/v1alpha1
  kind: WildFlyServer
  metadata:
    name: quickstart
  spec:
    applicationImage: "quay.io/wildfly-quickstarts/wildfly-operator-quickstart:18.0"
    replicas: 1
    storage:
      foo: bar
  

The PVC created by user is reused by operator.
