[tor-relays] Relays vulnerable to OpenSSL bug: Please upgrade

I've updated OpenSSL, deleted the keys on my exit per the
recommendations, and restarted the whole box. I got a new fingerprint.
I'll watch to see how long the flags take to come back, but I predict it
will be like a new relay. I wonder how this changes the flow rates
across the Tor network. Perhaps adversary-controlled exits may not be
upgraded so that they can keep their percentage advantages and take
advantage of the disruption. In due time things will come back to normal.

I'd recommend that every relay operator delete their keys as well, just
to be safe. Pure speculation on my part here, but a well-resourced
adversary might have seized the moment and done some attacking, or
perhaps they knew about it beforehand. This is a major vulnerability.
Admins are revoking SSL certificates, and that's for web servers. The
blog post is very helpful for outlining how this exploit affects us, but
let's assume the worst here.

While we're updating, how about we all make sure we are running the
0.2.4 series of Tor, preferably 0.2.4.21. Switch to the Tor Project's
repositories if you haven't already.

Good luck guys.
