## Changes
Rewrite bundle/tests/python_wheel_test.go into acceptance tests. The
same configs are used, but the test now runs 'bundle deploy' and in
addition to checking the files on the file system, also checks that the
files were uploaded and records jobs/create request.
There is a new test helper bin/find.py which filters out paths based on
regex, asserts on number of expected results. I've added it because
'find' on Windows behaves differently, so this helps avoid
cross-platform differences.
