Metrics Stability Enhancement

[logicalhan]

Enhancement Description

• One-line enhancement description (can be used as a release note): Introduce a framework for providing stability guarantees for Kubernetes control plane metrics.
• Kubernetes Enhancement Proposals: Metrics Stability Framework, Metrics Validation and Verification, Metrics Migration
• Primary contact (assignee): @logicalhan, @serathius
• Responsible SIGs: sig-instrumentation
• Enhancement target (which target equals to which milestone): This isn't a feature per se, but we intend to have the metrics migrated as of 1.16. The migration itself will be a backwards compatible change.

@logicalhan How is this different than #1206? Is this an on going genesis of #1206? Or is this a completely new Enhancement?

We need to find an umbrella issue for this if this will be in 1.16

@kacole2 This is someone different effort driven by different people. "Kubernetes Metrics Overhaul" is about unifying how metrics are written. This effort is about introducing stability to
K8s metrics by introducing new library.

@serathius I think there is a disconnect. There needs to be an issue created for each type of Enhancement. I see 3 KEPs here. We've never had 3 KEPs assigned to a single issue.

Can we update the title to be more descriptive? Can we also update the description to be more descriptive of what this enhancement should be tracking? Do all 3 KEPs align to this "single" enhancement?

The way I see it.

1. Metric Migration is one issue (is this Kubernetes Metrics Overhaul #1206 ?)
2. New Metric Library is another issue. (is stability part of this? and it needs to be called out in graduation criteria in the KEP)

We are actually going to merge these under the metrics overhaul KEP, since the stability work is (at this point) a precondition of the overhaul metric deprecation.

I'm going to reopen this as the original tracker for metrics stability, as it's still in beta and hasn't GA'd
