Fix #1019

Related to https://issues.redhat.com/browse/CRW-5722

Is it tested? How?

• Create this DevWorkspaceConfig that provides storageAccessMode for ReadWriteMany

apiVersion: controller.devfile.io/v1alpha1
config:
  enableExperimentalFeatures: true
  routing:
    clusterHostSuffix: 127.0.0.1.nip.io
    defaultRoutingClass: basic
  workspace:
    imagePullPolicy: Always
    storageAccessMode:
    - ReadWriteMany
kind: DevWorkspaceOperatorConfig
metadata:
  name: external-dwoc-test

• Create a DevWorkspace using abovementioned workspace config:

kind: DevWorkspace
apiVersion: workspace.devfile.io/v1alpha2
metadata:
  name: theia-next-external-dwoc
spec:
  started: true
  template:
    attributes:
        controller.devfile.io/storage-type: common
        controller.devfile.io/devworkspace-config:
          name: external-dwoc-test
          namespace: devworkspace-controller
    projects:
      - name: web-nodejs-sample
        git:
          remotes:
            origin: "https://github.com/che-samples/web-nodejs-sample.git"
    components:
    - name: tools
      container:
        image: quay.io/devfile/universal-developer-image:ubi9-latest
        memoryLimit: 256Mi
        mountSources: true
    commands:
      - id: say-hello
        exec:
          component: theia-ide
          commandLine: echo "Hello world"

• After applying these manifests, check the PVC created should have the same accessMode as specified in DevWorkspaceConfig:

oc get pvc external-dwoc-pvc -o=jsonpath='{.status.accessModes}'
["ReadWriteMany"]
