[pbs-devel] [PATCH proxmox] router: sort cli properties in usage output

[Dominik Csapak]

If we don't do this, then properties from a serde flattened struct will
be positioned at the end of the list, rather than properly sorted with
the other properties.

Since the tests also feature non-sorted properties, we have to adapt
them too.

i wanted to add tests for the serde flattened structs, but the test
don't use the api macro, nor serde, so i was not sure how i could
replicate that. If somebody has an idea for that, please tell, then
I'll send a v2 or follow up
