Environment labels

You can now attach arbitrary key/value labels to environments and use them to group, filter, and search the environments list. Tag environments by tier, region, customer, team, or any axis you need to slice by. Add labels from the environment create page or the Settings tab, then group by tier, filter by region=us-east-1, or search by label key or value from the environments list. The same labels flow through YAML and the CLI, so Git sync keeps them in step with the rest of your environment config.
