Add custom label to all objects in kubernetes chart

[TheCubicleJockey]

Expected Behavior

This chart improvement would allow the user to include a defined label in the value.yaml, and that label would be included in the kubernetes objects in metadata.label where allowed by kubernetes.

Current Behavior

Nothing like this is allowed in this chart.

Possible Solution

Anything that allows user defined labels in the kubernetes objects. Using something like commonLabels at the top level of the values file.

Steps to Reproduce (for bugs)

1. N/A

Context

Labels are good in kubernetes for organization and for some custom tools that read labels as a part of rule sets.

Am I good to make the PR?

@TheCubicleJockey right now, there is support for podLabels: https://github.com/projectcalico/calico/blob/master/charts/tigera-operator/values.yaml#L49-L50

Would you propose a new field that is merged with podLabels?

[TheCubicleJockey]

My use case is for the clusterrole to have a label. So, I could make one specifically for the clusterrole, but I figured most charts have a values.commonLabels or a values.additionalLabels as a more generally acceptable version that would fit most need and my needs.

If i am doing the work, i would like to help improve the chart in a way that you or your team might like it improved.

[caseydavenport]

Yes, I think values.additionalLabels seems like a a good way to spin this, SGTM!
