exchange: expose bundle2 capabilities on pulloperation

This adds a cache and makes accessing the capabilities slightly simpler,
as you don't need to directly go through the bundle2 module. This will
also help prevent a function-level import in streamclone.py.

This patch arguably isn't necessary. But I think it makes things
slightly nicer.
