[pbs-devel] [PATCH v2 proxmox-backup] api: add dedicated storage name schema

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

Introduce a dedicated storage name schema to semantically distinguish
between datastore name and storage name.

Further, adapt the systemd mount unit description accordingly.

Signed-off-by: Christian Ebner <c.ebner@proxmox.com>

changes since version 1:
- s/DATASTORE_DISK_SCHEMA/STORAGE_NAME_SCHEMA/
- Adapt schema and systemd mount unit description
- s/datastore_name/storage_name/ for `create_datastore_mount_unit`
