Enable nicFirmwareStorage Storage ReadWriteOnce #123
Description
When using the Network Configuration Operator and configuring the nicFirmwareStorage section of the custom resource if create is set to true to create the PVC the logic in the code expects the storageclass to have ReadWriteMany. However there are use cases like Single Node OpenShift using LVM Storage where only ReadWriteOnce is available.
Currently one can work around this by setting create to false and pre-creating the PVC as a ReadWriteOnce. However it would be more elegant to pass the volumemode to ensure when using create true I can generate the write PVC.
At the very least maybe calling this out in api documentation that it only supports ReadWriteMany would avoid delays in getting the operator up and running.
