[PATCH proxmox-backup v3 14/15] tape: use proxmox-product-config to generate create options

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

Instead of redefining them, use the global helper defined in
proxmox-product-config. Requires the crates init function to be
called exactly once before using in any callpath.
