Consider to use GraphQL types in the singular

[orpheuslummis]

IMO, collection names are best expressed as singular for the (most usual) case in which every document represents 'one object'.

Plus it is inconsistently used currently, sometimes it is singular other times plural

[fredcarle]

Technically, since a collection represents a group of objects, it should probably be plural. If we follow GraphQL convention, since we return a list, the name should be plural. The schema however can be singular. How we best achieve that is subject to discussion.
