Sometimes it is useful to get information about an object without having
to download it completely. The server logic has already been implemented
in “a2ba162cda (object-info: support for retrieving object info,
2021-04-20)”.
Add client functions to communicate with the server.
The client currently supports requesting a list of object ids with
feature 'size' from a v2 server. If a server does not
advertise the feature, then the client falls back
to making the request through 'fetch'.
