class GraphqlMigrateExecution::DataloaderShorthand

These fields can use a dataload: ... configuration. They use a single, simple dataloader call:

dataload_assocation(...)
dataload_record(...)
dataload(...) or dataloader.with(...).load(...)

and they don’t make calls on self inside those expressions (except for object and context).
