Comparison updates might involve some custom fetch process, so provide a
mechanism to register these via settings.py on a per-branch basis. If
an update command is defined for a branch and the logged-in user has the
new "update_comparison_branch" permission, an "Update" button will show
up on the recipes page for the comparison branch for authenticated
users that will trigger the command in the background (as a celery job)
and then show a page that displays the status. The status isn't shown in
real-time since that requires quite a lot of plumbing, but the page at
least auto-refreshes.

This patch adds asynchronous task execution using a Celery backend
and RabbitMQ task queue, so that the layer submission process to
proceed even in the event that sending the notification email fails,
and establishing an asynchronous execution mechanism that we can use
in the future e.g. for triggering parse operations from the web UI.
This pertains to bug 11197:
https://bugzilla.yoctoproject.org/show_bug.cgi?id=11197
It updates the README to reflect the installation and configuration
of a basic RabbitMQ setup, adds a 'tasks.py' file to contain task
definitions, updates the 'edit_layer_view' function to send
emails to administrators about new and updated layers asynchronously,
modifies the 'settings.py' to include a default configuration
for a RabbitMQ connection, and updates the Dockerfile to start a Celery
worker alongside the Gunicorn daemon.
Fixes [YOCTO #11197].
