When using the multiprocessing module, it throws an AttributeError,
complaining that the object does not have the attribute used. This adds
the missing attributes and allows them to be pickled.

The py2-ipaddress module unfortunately conflicts with the pypi:ipaddress module, which is in the dependency tree of widely used pyOpenSSL. I think it would be a good idea to use a well maintained backport of the Python 3.5 implementation of match_hostname() instead of duplicating the effort and maintain another.

All tests are passing here.

If you have assert_hostname turned off and are using a proxy on your
computer then assert_hostname wasn't being properly set on the pool
connection and it was failing to connect to docker

Up to TLS 1.2, support the highest locally supported crypto
protocol. This eliminates the previous default of PROTOCOL_SSLv23,
replacing it with what should be TLSv1 for Python 2.7 and TLSv1.2
for newer versions of Python 3.

Developers using docker-py may still specify the ssl_version to
override the default.

- Check that `urllib_ver` is not None, instead of `urllib3`
- Do version comparison only if `urllib_ver` is *not* "dev"

Fixes #325. Original work by @sidprak.

Expanding on @denibertovic initial additions, we now have full support for SSL in docker-py. Including the ability to specify the expected SSL Version for issues with OpenSSL sslv3/tls1 recognition issues. Added an exception class for repetitive reminders to look at the CLI doc on docker.io.
