I think `git pack-refs` would work for reftable backend. It would
eventually call `reftable_be_pack_refs`. And from my intuitive
understanding, it would compact the reftable to reduce the size of the
table.

If my above understanding is correct, "git pack-refs" has already worked
with all the backends. But for reftable backend, the semantic of
"pack-refs" is not clear, optimize is a much better semantic word.
