Can no longer create a context with specific ciphers #1462
Description
The recent change to remove support for Python 2.6 has made it so that the "ciphers" parameter of the create_urllib3_context function in ssl_.py no longer has any effect. The parameter is unused for the rest of the function.
This was working properly in Python 3.6, so I don't know why it was tagged as being Python 2.6 specific.
