Run e2e test on BTP Manager installed from template.yaml

[PK85]

Description

This ticket is about changing the way how to install BTP-Manager in our: https://github.com/kyma-project/btp-manager/blob/main/testing/go/e2e_test.go. Instead of make deploy we must install BTP Manager in the same way how Lifecycle Manager does.

Of course, testing Lifecycle Manager is not in our scope, which means we need to reuse ~~our generated template.yaml~ OCI image and out of that install BTP-Manager for testing purposes.

AC

• 1) Generate module for PRs that results with template.yaml OCI image
  • 1.1) find a way where to store template.yaml for PR pipeline, that will be required for next steps this is not longer necessary since OCI image is stored in registry
• 2) Adjust release pipeline to use the same way of storing template.yaml as in PR (Still keep template.yaml in the release itself) not valid any more, we are not storing template.yaml in PR
• 3) download OCI image, unpack it, install
• 4) describe in our documentation how and what is tested in our e2e tests
• 5) try store OCI images and templates in the local registry (we use k3d for testing)

During discussions with @PK85 and @piotrmiskiewicz we agreed to use OCI image only, not to use template.yaml

Prow job - creating OCI module image for PR (presubmit job) - merged

[jaroslaw-pieszka]

Initial version - stub of script creating the module image (via make invocation) - merged

PR

• waiting for module image being pushed to registry in the pipeline
• testing helm install
• testing helm uninstall
• applying prerequisites (namespace, priority class, sample operator)
