Create Namespace: add static labels to namespace

[smerschjohann]

This change adds the ability to add labels to namespaces during creation. These labels can be configured in the config.json of the dashboard.

Description of the change

• Added labels to the grpc proto of the resources.proto
• passed these labels to the Kubernetes Manifest
• added createNamespaceLabels to the Dashboard configuration
• passed these values to the "createNamespace" method
• added the newly introduced config parameter to the Helm-Chart

Benefits

See Issue

Possible drawbacks

Current default behavior left unchanged.

Applicable issues

• fixes Create Namespace: add static labels to namespace #4922

Additional information

I seem to have a slightly different buf binary, as it produced a lot of changes in the generated code. I commited that as is, but as a seperate commit. I'm not sure how to solve that.

I was also unable to get the newly introduced field into the openapi spec. What am I missing here?

Thanks for the contribution! We are currently in the middle of a release process (v2.4.6) and therefore we have a bunch of PRs pending review. We'll get to it as soon as possible! Anyway, it looks pretty good at a glance, thanks for the effort!

Great! Outstanding contribution: from a change in the proto file definition to the frontend code, besides changing the chart and other files. Well done!

Just for you to know, we are using this project for autogenerating the readme.md, this way, each param you add to the values, will get auto-documented. No need to execute it for this PR, we can do it later.

I only have a minor comment (adding a test case), but otherwise, LGTM.

@antgamdia ok, I added the test and rebased the PR to the latest changes
