This PR
- Adds changes to only start/stop the celery workers on appserver activation/deactivation. This prevents the unit tests related to Consul from being skipped. This has to be tested and verified on stage.
- Fixes the consul configuration which was breaking unit and integration tests - enables consul encryption for the integration tests and the cleanup job and runs consul in dev mode for everything else.
- Increases the retries and the delay between retries when checking whether the integration test instance is up or not. Also adds logging to show the retries.
