Refactor integration E2E tests

* General cleanup of the integration tests Golang code. Move the
  `e2e.go` codebase into its own package and separate files.
* Reduce the overall log spam from the integration tests output.
* Add final GitHub workflow step that stops GARM server, and does the
  GitHub cleanup of any orphaned resources.
* Add `TODO` to implement cleanup of the orphaned GitHub webhooks.
  This is useful, if the uninstall of the webhooks failed.
* Add `TODO` for extra missing checks on the GitHub webhooks
  install / uninstall logic.
