Removing jobs for unsupported release branches

[sbueringer]

Context

Currently we run tests for all release branches since v0.3, but actually supported are only v1.2 and v1.3.

Motivation

Let's focus on maintaining test jobs of relevant releases. It's not worth the effort to maintain branches of releases which have been out of supported for a while. Especially as they start failing over time for reasons unrelated to Cluster API (e.g. registry migration).

Proposal

Policy:

Let's only keep jobs of the currently supported releases and 1 additional release in case we have to do an emergency patch release.

Now let's apply the policy to our current jobs:

• We keep the jobs for:
  • release-1.3 => still supported
  • release-1.2 => still supported
  • release-1.1 => we keep the job for one more release cycle, they will be dropped after the v1.4.0 release
• We remove the jobs for:
  • release-1.0, release-0.4, release-0.3: they are out of support for longer than one release cycle.

Tasks

• Document policy and update release tasks: 📖 docs: document test coverage for release branches #8118
• Drop jobs in test-infra: CAPI: Remove jobs for unsupported release branches kubernetes/test-infra#28808

I am also happy to help with the clean up, once we agree with all community members (including downstream).

Thx! Sounds good. I've assigned the issue to myself in the sense of that I want to ensure that the issue makes progress / is implemented. Happy to delegate the implementation / collaborate on the implementation

yay! this is a nice cleanup, it contributes to the log term health of the projects and it also helps the K8s community in the effort of containing infra costs.

[sbueringer]

I've opened a PR to document the policy and update the release tasks: #8118

Once this PR is merged someone can open a PR to drop the jobs.

[sbueringer]

I'll merge #8118 tomorrow.

@furkatgofurov7 @cpanato One of you can prepare the PR to drop the jobs for <= v1.0 if you want. (including the dashboards)
