This PR documents an additional restriction for attaching a custom storage volume: you cannot attach a storage volume from a local pool to an instance that has migration.stateful set to true. You must set it to false first, which results in the instance becoming ineligible for live migration.

Closes canonical/microcloud#717

Thanks! I have created canonical/microcloud#846 to cross-link this also from the MicroCloud docs.

MicroCloud should consciously set the instances.migration.stateful key
