added checksum/config annotation to ensure pod restarts when new config is applied

[darkedges]

When the following is run after making a config change.

helm upgrade --install topaz . -f topaz.yaml --namespace topaz --create-namespace

helm will restart the pod so that the new config can be applied.

kubectl get pods -w
