5.0.0

aio app logs used to return logs from all actions in the current namespace.
Now it looks for manifest.yml and returns logs for only the actions defined in the manifest.yml and throws an error if there is no manifest.
This is in true sense of app. To see logs from other actions (not defined in the manifest), use aio rt logs.
