What would you like to be added:

I would like the label reason to be added to the kube_deployment_status_condition metric.

Why is this needed:

The kube_deployment_status_condition has only two properties relating to the DeploymentCondition object: condition and status, which is not enough to distinguish between a Progressing Deployment and a Complete Deployment. The reason label will add sufficient information to distinguish the two states.

Describe the solution you'd like

Simply extract and emit the reason label for the deployments.
