We want to help users configure their pipeline configuration to enable jobs related to Container Scanning analyzer. With this change we are introducing backend changes that allows them to do it with single GraphQL mutation.

How to set up and validate locally

1. Create new project
2. Go to GraphQL Explorer
3. Trigger a mutation:

mutation {
  configureContainerScanning(input: { projectPath: "root/ds-test-2"}) {
    branch
    errors
    successPath
  }
}
