A mutation to create a new Milestone on a specific Roadmap.
As with in-app behaviour, you must specify a summary (Milestone Name) when creating a new Milestone. Given that Milestones are associated with a single, specific roadmap, a roadmapID must also be specified in order to create a new Milestone. All other fields are optional.
A Milestone can only have a single date. It cannot include dates ranges (Start and End Dates) or a bucket time.
