get a legend for haproxy "anomalous session termination states"
Open, MediumPublic

Description

On the grafana dashboard for haproxy:

https://grafana.wikimedia.org/d/pr6ZUm5nz/haproxy-cluster-view?orgId=1&var-datasource=eqiad%20prometheus%2Fops&var-cluster=text&from=now-3h&to=now

We want to get a legend for the "anomalous session termination states".

It should at least be on Wikitech and ideally on the dashboard itself.

@RLazarus The dashboard in Grafana now has links into Wikitech where we have copied a list of the session states.

This is a better link since it's directly upstream and latest docs from 2022:

https://www.haproxy.org/download/2.7/doc/configuration.txt

^ it's the entire section"8.5. Session state at disconnection"

just not as nice to link to as the HTML on github.io.

edit: updated links and info on wiki with the 8.5 section from above
