Conceptually, GraphQL operations (queries/mutations/subscriptions) are a
special case of field resolvers that happen to be on well known root types.

Technically, this means that everything about field resolvers is the same
as these root types resolvers, apart from the fact that the former get an
instance of the resolved type as first param.

Therefore, all the configuration that applies to field resolvers also
applies to resolvers of the fields that are part of these root types, like
CompletableFuture return type, or DataFetcherEnvironment parameter.

This makes use of the MultiSourceReader provided by the graphQL library.
Using this reader allows to read a single document from multiple files,
while correctly associating line numbers and errors to their original
source file.

This doesn't bring any overhead because the method Parser.parseDocument(String) that was previously used already created a MultiSourceReader itself.
Note that the previous method didn't associate the source file name with the content used for parsing, while the new one does.

It allows to solve cross-reference problems with union types for instance.
