Support parallel deployments

The current implementation for flexible deployments in Pipelines allows us to define multiple Test, Staging and Production deployments However, all deployments in a specific phase (e.g. Production) have to be executed sequentially. In our case, we have multiple production deployments for multiple countries (Kenya, Tanzania and Nigeria). With the current setup, we are forced to deploy to all production deployments sequentially (only one ‘Deploy’ button is clickable).

We would like to propose a change in the UI, where the user can trigger any manual deployment for a specific phase. (e.g. we would like the ability to deploy to Production-Nigeria without having to deploy Production-Kenya first).
