Charts updates to add global labels

[ianarsenault]

This PR updates the following charts to add global labels to the resources deployed within the chart

• charts/snowplow-iglu-server
• charts/priority-class
• charts/daemonset
• charts/cron-job
• charts/cluster-warmer

Overall LGTM. If you haven't, I'd run these all through a helm template to ensure everything is rendering nicely both with and without the presence of labels.

Good call @jparavisini . I've made some updates to account for trailing whitespace Have run them through helm template with and without passing labels

Example with priority-class

➜ helm template priority-class priority-class
