[pbs-devel] [PATCH proxmox{, -backup} v2 0/7] introduce streaming content api call

[Dominik Csapak]

This series introduces a new api call `content` on a datastore that
returns the whole content recursively, including namespaces, groups and
snapshots.

It's doing that using the proxmox-router::Stream, so a client can get
the separate records without having to wait for the api call to finish.

This is intended to improve ui responsiveness, since we can show things
even when it's still loading. This can be very useful for large
datastores.

This series contains some refactorings that were necessary, but also
includes one performance improvement for the `groups` api call (stumbled
upon it during testing)

changes from v1:
* remove content type filter from api call (we can decide later how/if
  we want to filter that)
* remove use of exlicit async-stream (can be done via
  proxmox-router::Stream)
* send errors to the stream too
* rename namespace helper
* restructure finding the first finished backup in
  `backup_group_to_group_list_item`
* rename '*List' structs to have more concise names
* return the next level of namespaces in listing
