Migrate Prow jobs to Github Actions

[tobiscr]

Description

As Prow will be discontinued in 2024, we have to move the Prow jobs used for the Application Connector Manager to an alternative CI/CD system. In our case Github Actions is the preferred choice.

Overview of all existing Prow-jobs is listed here: https://github.com/search?q=repo%3Akyma-project%2Ftest-infra+framefrog&type=code&p=1

AC:

• [x] https://github.com/kyma-project/application-connector-manager/issues/267
• [x] Identify which of the jobs listed in the URL above are required during the Application Connector Manager development-lifecycle and relevant in the longterm (have to be migrated)
• [x] All Application Connector Manager related Prow jobs are migrated to Github Actions
  • [x] Test jobs are migrated to GHA
  • [x] Building jobs are migrated to new image builder
• [x] Test infra has no references to application-connector-manager

Reasons

Migrate CI/CD jobs from Prow to Github Actions as Prow will be discontinued in 2024.
