Apply Step group

The step-group workflow step creates a subgroup of steps that will be executed sequentially. This is useful for complex workflows to simplify the inter-relationships and dependencies.

The following snippet contains an application with a step-group workflow step to deploy the components one after the other, and after that send a notification to Slack.
