Ability to enforce a specific version of TLS protocol

[bkazula]

Hey, I needed support for a specific version of TLS (TLS1.2), with that PR everyone will be able to enforce the desired ssl protocol.

Thanks a lot for your contribution! I like the idea, and the code looks quite good so far.

Here is the result of a quick review:

• Please use a separate commit for fixing coding style issues such as the spacing issue in line 77.
  • Already done as part of another unrelated cleanup. Please rebase your pull requests.
• The usage of the names protocol and ssl_protocol is inconsistent and confusing, so:
  • Please rename the imported default protocol to default_ssl_protocol, perhaps in a separate commit.
  • Then, please use consistently ssl_protocol for all parameter names.

As soon as this pull request is finished, I'll publish a new release of requests_pkcs12 immediately.
