Increase retention time of graphite stats for CI

Description

My current need is for gate-and-submit. The data doesn't exist pre-6 months ago:
https://grafana.wikimedia.org/d/000000108/releng-kpis?orgId=1&from=now-6M&to=now&fullscreen&panelId=18

This is preventing me from reporting on our work effectively.

In other panels I see data going back to Aug 2017 for core's gate-and-submit, e.g. https://grafana.wikimedia.org/d/000000108/releng-kpis?orgId=1&from=1496046004105&to=1579080951474&fullscreen&edit&panelId=2 maybe it has to do with the panel's query ?

tentatively assigning to greg to see if he can figure out what's going wrong with that panel. Reassign as needed :)

My guess is that it has to do with me trying to get ALL metrics vs just mw/core:


(Yes, they're "disabled" aka not shown, but they're referenced later down when doing the std deviation etc)

So, there's probably some metric that only goes back to ~6 months and that's limiting the overall summary.... hmmmm.

I want all metrics, but I want it to go back as far as it can.

@fgiunchedi do you know of any options of doing that?

No idea @greg right off the bat, although I see the panel Gate and Submit "Resident Time" on top left is working as expected so I take it is possible in some fashion

So yeah, my previous comment is right and I'll just need to fiddle with metrics to get them to give me what I want when I hit this issue.
