Docker client server mismatch versions

[Artur Zarzycki]

On kolla-build there is error:

Exception in thread Thread-1:
Traceback (most recent call last):
  File "/usr/lib64/python2.7/threading.py", line 811, in __bootstrap_inner

APIError: 400 Client Error: Bad Request ("client is newer than server (client API version: 1.21, server API version: 1.20)")

It's because Docker version used by kolla is fixed to 1.8.2 (API 1.20) and 2 days ago was released docker-py 1.6.0 (API 1.21).
So there is need to pin the docker-py version in requirements and dev/vagrant/bootstrap.sh.
