There are a bunch of places where the narrative text say things like
"jenkins runs jobs". This hasn't been true for a while and it's getting
less true.
Left third-party and running-your-own alone because those are
instructions for other people to do things - and we are not yet at the

things.
The devstack-gate document describes an old deprecated system, but the
system is still in use (sadly) so it was mostly left intact. A warning
was added so that people would be clear that it was deprecated.
Also removed the logstash client config file. It's the only change in
here that actually affects running code and became unnecessary when it
was switched to geard with Ie3f814e6d3278d87f2a20a72e40b6b92217684fc
