[pve-devel] [PATCH storage 4/9] api: status: rely on get_formats() method for determining format-related info

[Fiona Ebner]

Rely on get_formats() rather than just the static plugin data in the
'status' API call. This removes the need for the special casing for
LVM storages without the 'snapshot-as-volume-chain' option. It also
fixes the issue that the 'format' storage configuration option to
override the default format was previously ignored there.
