// this if() fixs direct use of PVC reference inside spec.template.spec.containers[0].volumeMounts
// instead of referencing the PVC the "good way" using spec.template.spec.volumes array
// Basically it creates an "in-memory" reference for the PVC, as if it was saved in
// spec.template.spec.volumes and retrieved from here.
//
// FIX FOR SFS ONLY ; as far as we know it's not possible to do this with DEPLOYMENTS/DAEMONSETS
//
// This may lead to destructing behaviours when we will allow external apps to be edited.
// E.G. if we try to generate the formValues and patch the app, SFS reference will be created under
// spec.template.spec.volumes and not be referenced directly inside spec.template.spec.containers[0].volumeMounts
// As we preserve original SFS name and try to build around it, it SHOULD be fine, but we definitely need to test this
// before allowing external apps modification
