Our current node labeling process limits us to one node type per node (e.g. compute, loadbal). We should be able to change the labeling to allow all label types on a single node to run all services.

This ticket is complete when:

1. We have discussed alternative strategies for node labeling
2. The Labs Workbench apiserver has been updated to respect the new labeling scheme
3. The templates within ndslabs-deploy-tools and ndslabs-startup are updated to respect the new labeling scheme
4. kube-up.sh in ndslabs-startup and ndslabs-k8-init-labels/tasks/main.yml in ndslabs-deploy-tools have been updated to correctly apply the new labels
