Add beat worker to the deployment.

We will run a separate pod for the beat worker. There should only ever
be a single beat worker (to avoid redundant work) so the number of
replicas needs to be managed independently.

This adds both the Kubernetes config for the new pod and additional
CircleCI config to swap a new image into the pod during CD.
