Merge lp:~thomir-deactivatedaccount/core-image-watcher/trunk-use-request-id into lp:core-image-watcher

[Thomi Richards]

[Celso Providelo (cprov)]

Let's use the kombu UUIDv4 accessor for peace of mind here.

I will pre-approved it because I probably won't be here when you come from lunch.

review: Approve
