chart: new additionalLabels for podMonitors and PrometheusRules

[ymettier]

Signed-off-by: Yves Mettier ymettier@free.fr

This PR allows to specify additionnal labels on podMonitors and PrometheusRules.

This is needed when you are using Prometheus-Operator and when you configured it to use specific podMonitors and specific PrometheusRules using a specific label.

Important note : I have not bumped the chart version in Chart.yaml (because I don't know when you may merge this PR).

@gclawes FYI

Values.schema.json should be updated whenever new fields are added to values.yaml. @ymettier let me know if you need help with this, or would like me to add a commit to this PR myself.

On the subject of Chart.yaml versions, this is incremented by the MetalLB release process, and not individual PRs for the charts.

[ymettier]

I guess you will do it faster and better than I. @gclawes thanks in advance if you can do it : feel free to add a commit !

@russellb I've pushed the relevant changes to value.schema.json and Chart.yaml to https://github.com/gclawes/metallb/tree/additionalLabels

Thanks, @gclawes . This is a nit for the future, but maybe we should change "0.9.6" to something else, like "0.0.0" ... I just thought of this, but now this version in main is behind what's in the v0.10 branch, since that automation just updates the release branch.

[gclawes]

Yeah, that makes sense.

[russellb]

Thanks, everyone. I'm going to wait for tests to all pass, but I'd also like to add something to the release notes. I'll handle the release notes part.
