feat(github): Analyse past release times

[tico24]

I'm far from a python expert so please don't laugh too much.

I wanted to understand whether or not we are releasing at a faster pace than before (given we are a more organised team and we have automation in the likes of Renovate now).

This script calculates the release time for each upstream release and plots the values on a graph.

Checklist:

• I have bumped the chart version according to versioning
• I have updated the documentation according to documentation
• I have updated the chart changelog with all the changes that come with this pull request according to changelog.
• Any new values are backwards compatible and/or have sensible default.
• I have signed off all my commits as required by DCO.
• My build is green (troubleshooting builds).

Sadly my python knowhow is even worse :D I totally missed that Python era - I am still on pure bash or Go ^^

Shall we present the output of this on the GH pages over there?
https://argoproj.github.io/argo-helm/ (maybe under /stats or so)

short answer is “yes, eventually, but not in this PR”.

We should use gha to build the data as we go rather than this expensive query for the whole history. Once we have that then we can look into publishing.

Could I get some reviews please?

I am okay with that :) 👍
Do the Argoproj maintainers have any plans on the SLA? I saw the SLA graph and I am curious if it is only an assumption by you ( @tico24 ) or if it comes from the project.

[tico24]

The SLA comes from a time that @jmeridth told me. But I can't find it written anywhere.

[mkilchhofer]

@tico24 maybe documentation regarding what permissions the PAT requires would be nice, WDYT?

[tico24]

Ah yeh I'll do that. It just needs public read, so super minimal.

[mkilchhofer]

Do we have a explanation why we have two negative data points?

(that negative number for argocd is somehow correct... I released the helm chart before the upstream version was released... I have no idea why).
