ci: enhance build.yml workflow

[Abhinandan-Purkait]

Workflow in detail

• A user PR gets merged to the develop or release/x.y branch.
• The concerned GitHub action workflow kicks in on the PR.
• First, it checks out and sets up the runner.
• It then runs the lint. Lints include helm lint.
• Verify the chart version, it should be of the format x.y+1.0-develop or x.y.z-prerelease. If it’s anything else, the workflow fails.
• Extract the chart version from the chart. This tag would be used for building the image locally.
• Build the images using the code in the branch and tag it with x.y+1.0-develop or x.y.z-prerelease.
• Set up the minikube cluster.
• Execute the CI tests by installing the helm chart from the deploy/helm/charts directory. Set the image pull policy to Never since we are supposed to use the images built in the previous step.
• Execute the CI tests. We are to use the helm chart here.
• If the test passes the CI succeeds else it fails.
• Push the images to the docker hub registry ?
• Package the helm chart and push it to the gh-pages ?

NOTE

This PR removes the ansible step, that used to create image for e2e-test. e2e-test for openebs engines are now supposed to be carried out in the https://github.com/openebs/openebs-e2e repo going forward.

Will the release-charts changes come later?

You'd have to document the removal of the ansible build and push e2e image on the PR description or commit message.
