The API changed slightly.

Use the ubuntu keyserver to retrieve the edX PPA key.

Explicitly set the permissions for the supervisor config for celery.

Upgrade to 3.0.14

The sed -E still doesn't work on OS-X

Feanil/fix notifier celery process leak

Ansible2 compatibility and jenkins plugin updates
