[PATCH pve-storage 3/9] storage: add `unknown` flag to parse_config

[Jakob Klocker <j.klocker@proxmox.com>]

While the base class provides an `unknown` flag it wasn't possible to
get unknown storages through the storage parse_config function. With
the added flag it is now possible to access these.
