Introduce Workflow, Drafts, and API
The Commitfest Workflow is a formalization and extension of the existing commitfest-only protocol. There is now some in-app documentation and the idea of moving patches to the "next CF" has begun being deprecated. Instead the UI provides the user valid choices on where to transition patches, which, with the introduction of the Drafts commitfest, is basically one or the other. Committers gain the ability to transition patches into In Progress if desired. Patches within In Progress commitfests can be moved into either Open or Drafts. Begin enforcement of a maximum of one commifest in each of Parked, Open, and In Progress. The workflow defines the drafts commitfest as lasting for one year matching up with the major release process. Namely, once the commifest leading up to feature freeze is In Progress a new Drafts commitfest should be created. With the workflow changes it is necessary for CFBot to be made aware of the specific commitfest ids that are active. Provide a JSON API for this purpose to begin weaning CFBot off scraping html. The workflow in-app documentation includes a month-based schedule showing which commifests are active, and their names, in each month (among other related details). Begin enforcing the existing rule that future commitfests cannot have patches via triggers. Future work on the administrative and UX aspects of the CFApp likely will do away with future commitfests altogether. Thoughts on the topic are welcome in the GitHub issues.
