Requirements

Day 2 Configurations for applications are applied using K8S kinds (typically CRDs) implemented by application specific operators.  For a given application, type of configuration is similar (but not the values), therefore configuration templates are created by applications.  These templates are for each application and are expected to be created even before Day 2 configuration is applied. Once the templates are created, configuration can be applied by choosing the right template. Day 2 configuration is applied by users as and when new configuration is required. As a user, he/she should select the template and supply values to apply new configuration.
