"%(objecttype)" is already known by the client's allow-list, but neither
the client nor the server knows how to handle type. This series continues
the work for git cat-file --batch-command extending remote-object-info
to support "%(objecttype)" end to end. It is based on its predecessor
series "cat-file: add remote-object-info to batch-command" [1].

Type is the last property that is identical on the server and on the
client once fetched.

Whether to support more metadata such as:

- objectsize:disk
- deltabase
- objectmode (needs context)

should be discussed, unlike size and type, the rest depend on how things
are packed on the server and on what the client already has, so they
cannot reliably match local once fetched. IMO they are not worth
supporting, I can't find a use case for them.

Adding new placeholders has become trivial.
To add a new placeholder, follow the steps in this series and add it to
the client's allow-list at 'builtin/cat-file.c'.
