[GSoC2024] update helm chart: Add common sub-chart

[abhi-bhatra]

Motivation and context

There has been multiple issue coming due to conflict in common chart version of Redis and Postgresql. Fixes #7449 Fixes #7507

How has this been tested?

1. Apply Helm chart with analytics enabled (Result: helm chart working)
2. Now, try to run helm chart again, with analytics disabled (Result: helm chart will get an error) Below is the error:

Error: template: cvat/charts/redis/templates/master/service.yaml:12:14: executing "cvat/charts/redis/templates/master/service.yaml" at <include "common.labels.standard" (dict "customLabels" .Values.commonLabels "context" $)>: error calling include: template: cvat/charts/postgresql/charts/common/templates/_labels.tpl:6:27: executing "common.labels.standard" at <include "common.names.name" .>: error calling include: template: cvat/charts/postgresql/charts/common/templates/_names.tpl:6:18: executing "common.names.name" at <.Chart.Name>: nil pointer evaluating interface {}.Name

@abhi-bhatra , could you please add a link into CHANGELOG.md? See instructions inside the file on how to do that.

@abhi-bhatra thanks for the contribution I have one question: Are you sure that the current versions of Redis, Postgresql and Clickhouse charts will be compatible with all future versions of common chart v2.x.x?

[abhi-bhatra]

Hi @azhavoro Thanks for looking at the contribution. I am sure about the version compatibility. I have checked version of common chart in all these 3 charts, and used the static version which will not create an ambiguity of choosing a version by other charts.

dependencies:
- name: common
  repository: https://charts.bitnami.com/bitnami
  tags:
  - bitnami-common
  version: 2.x.x

But, still I will run few more test by changing versions of common chart and will see that if it is compatible with Redis, Postgresql and Clickhouse charts.

Wouldn't it be better to pin the common chart version (or at least a minor version) in case of possible backwards compatibility problems in the future?

Also, probably need to add a simple test to sure cvat can be deployed without analytics, which would certainly help to quickly detect possible problems in the future.

@abhi-bhatra , will you be able to complete the PR?

[abhi-bhatra]

HI @nmanovic I am working on it, and will complete it by today EOD

@azhavoro I have pinned the common chart version, but I would like you to point me where to add test for helm charts ?

Should I create a bash script ?

I think it can be separate job in this workflow https://github.com/opencv/cvat/blob/develop/.github/workflows/helm.yml

[abhi-bhatra]

Thanks @azhavoro I am adding test case in this workflow. Thanks for guiding me !

[abhi-bhatra]

@azhavoro I have added a simple test case in the workflow, Can you review it ?

[azhavoro]

@abhi-bhatra Hello, the test example is not working, could you please fix it?

[azhavoro]

I can't merge this PR due to failed tests
