Specify Traefik version independent of image tag

Welcome!

• Yes, I've searched similar issues on GitHub and didn't find any.
• Yes, I've searched similar issues on the Traefik community forum and didn't find any.

What do you want to achieve with this Chart ?

Context:

• I build the Traefik container for internal deployment, which includes a custom plugin.
• My deployment strategy uses the git commit hash as an image tag to convey to the CD system which container image to deploy.
• The Traefik Helm chart requires semantic versioning in the image tag.
• I don't have a way to compose the Traefik version with the git hash in the CD system, without changing the config on the CD side. Deployment configuration is in a repo separate from the application code.

Current state: I have to change the deployment config in the CD repo when incrementing the Traefik version, in addition to the build configuration in the repo that contains the customizations.

I would love to be able to configure the Traefik version in just one place, in my internal Traefik repo. A variable for Traefik version, independent of the image tag, would fix the issue for me.

If this is a feature you're interested in incorporating, I'm happy to do the work.

@ashdwilson A possible fix in your use case would be to tag your custom traefik build with upstream version it's based on. Something like registry.io/traefik/traefik:v3.3.5-6c3b099

About your proposal, we’re unsure about the use case and the traction it will receive. We are going to leave the status as kind/proposal to give the community time to let us know if they would like this idea.

We will reevaluate as people respond.

@ashdwilson In fact, we need this feature for other specific use case with marketplace. We need to do it quite fast so I'll open the PR. If you have time to review it, it would be great.
