exchange: use rich class for sorting clone bundle entries

Python 3 removed the "cmp" argument from sorted(). Custom sorting in
Python 3 must be implemented with the dunder comparison methods on
types and/or with a "key" function.

This patch converts our custom "cmp" function to a custom type.

The implementation is very similar to functools.cmp_to_key(). However,
cmp_to_key() doesn't exist in Python 2, so we can't use it.

This was the only use of the "cmp" argument to sorted() in the code
base.
