[PATCH proxmox-backup v2 2/3] api: status/datastore: expose backend type in datastore status/list

[Christian Ebner <c.ebner@proxmox.com>]

Analogous to the mount status, include the backend type in the
datastore status list item and datastore status. This allows to
interpret the provided data based on the backend type and therefore
to switch elements on the ui such as labels.
