Describe the solution you'd like
The default behavior today is deploy the parent chart after all subchart are deployed and their dependencies are satisfied. In some cases it would require the parent chart to either go in parallel with the subcharts or before the subcharts are deployed. Provide a field in the ApplicationSpec that allows users to specify the order of deployment.
