feat: worker label

reason: without a unique label set, you cannot access the pods for a worker deployment uniquely. this is a flexible approach. should pass in the worker name as label?

this does not seem to correct the issue of:

kubectl logs deployments.apps/${release_name}-${worker_name} -n $KUBE_NAMESPACE

returns

Found 2 pods, using pod/${release_name}-${worker_name}-{slug}

pod-template-hash seems unique yet the logs call on a deployment picks up another deployment logs on the same tier.
