Singletons

[Noviny]

This pull request introduces Singletons as a new feature for configuring global, editable database entries when it's not necessary to have more than one representation of the schema (aka, not a normal list).

Singletons can be useful for things like:

• System Settings
• Homepage Layout
• Site Navigation

Before this feature, developers could write a typical schema for a list, and then using Keystone hooks limit the number of items within that list to approximate this functionality. Unfortunately the GraphQL schema didn't reflect these constraints, and neither did the AdminUI.

This pull requests brings that functionality native to Keystone's schema configuration as a first class primitive.

Tasks

• [ ] Add enforcement of the databases (where able) to ensure that the singleton list only ever has one item
• [x] Alter the graphql layer so that queries on singletons make more sense (remove querying for multiple items, remove the ‘where’ query on fetching a single item, as there will only ever be one)
• [x] Update the Admin UI - mostly subtractive changes to give a good experience for singletons where navigating items UI is removed, removing clicks

I am really looking forward to this feature. Are you able to estimate when singletons will be available in keystone?
