[CHANGE REQUEST] smolt retirement

[Toshio Kuratomi]

We've been talking about retiring smolt and replacing it with a sinkhole
that accepts data (so older installs don't cause long timeouts when
attempting to send a smolt profile) for a while now.  puiterwijk wrote the
files that we'd need to implement this a few weeks ago. I've now got those
changes we'll need into a patch against our puppet repo.

The changes touch the smolt server (value01) which is not covered by this
freeze and also the proxies which are.  In addition, I've got a second patch
that updates nagios to no longer check smolt.  The changes to main smolt are
applied in stg and seem to work well.  (Have tried smoltSendProfile against
the stg server and the links you are given for public profiles)

Can I get a +1 to apply these changes?

Note after freeze we can also:

* Turn off the smolt wiki -- the changes on the proxy should mean it doesn't
  see any more traffic but we should be able to stop it from running as
  well.
* Turn off backups of the smolt db
* Look into making the last smolt db dump available for people who are
  interested in the data.
* Remove the smolt db (and the smolt mediawiki db) from our mysql server.
