Transferring this from RHBZ#1576985

Description of problem:
The problem in the summary is because the version of s3transfer packaged right now is python-s3transfer-0.1.10-8.el7.noarch, whereas awscli is expecting 0.1.12; here is the requires.txt for the version of awscli packaged:

# cat /usr/lib/python2.7/site-packages/awscli-1.14.28-py2.7.egg-info/requires.txt 
botocore==1.8.32
colorama>=0.2.5,<=0.3.7
docutils>=0.10
rsa>=3.1.2,<=3.5.0
s3transfer>=0.1.12,<0.2.0
PyYAML>=3.10,<=3.12

And if you look at the Changelog for s3transfer, it's clear why 0.1.12 is needed:
https://github.com/boto/s3transfer/blob/develop/CHANGELOG.rst#0112

"enhancement:max_bandwidth: Add ability to set maximum bandwidth consumption for streaming of S3 uploads and downloads"

relevant commit (although this shouldn't be cherry-picked on its own):
https://github.com/boto/s3transfer/commit/61e387e361fe20c323f430970a22301906c90e8f



Version-Release number of selected component (if applicable):
python-s3transfer-0.1.10-8.el7.noarch
awscli-1.14.28-5.el7.noarch

How reproducible:
Always

Steps to Reproduce:
1. yum install awscli
2. aws s3 cp foo s3://bucket1/foo

Actual results:
__init__() got an unexpected keyword argument 'max_bandwidth'

Expected results:
Copy should succeed


Additional info:
If an update is not feasible, a patch would be sufficient:
