I've been seeing this deprecation in tests for a long time. Glad somebody came here to supply a fix. Looks good! Hope it gets merged in |

Issue #, if available: Fixes #4853.
Description of changes:
This was emitting deprecation warning from Python 3.4 and it will stop working in Python 3.9. Reference: python/cpython#10596. There is already awscli/compat.py so import ABCs from
collections_abcthat has Python 2 and 3 compatibility.By submitting this pull request, I confirm that you can use, modify, copy, and redistribute this contribution, under the terms of your choice.
And a heads up: you'll need to migrate off of Nose for testing, it's unmaintained and doesn't support Python 3.9: nose-devs/nose#1099. I'd recommend pytest.
