[Python-Dev] Disabling SSL 3.0

A big security breach of SSL 3.0 just dropped a little while ago (named POODLE).
With this there is now no ability to securely connect via SSL 3.0. I believe
that we should disable SSL 3.0 in Python similarly to how SSL 2.0 is disabled,
where it is disabled by default unless the user has explicitly re-enabled it.

The new attack essentially allows reading the sensitive data from within a SSL
3.0 connection stream. It takes roughly 256 requests to break a single byte so
the attack is very practical. You can read more about the attack here at the
google announcement [1] or the whitepaper [2].
