Refine exception handling and ensure a hierarchy of exceptions that
allows differentiating between transport errors vs field errors while
accessing an invalid data or field.

After the introduction of the `@GraphQlTest` annotation, this commit
adds further refinements to the testing infrastructure.
Now, `@GraphQlTest` is completely independent of any web framework and
contributes a `GraphQlTester` component.
`@SpringBootTest` integration tests with mock servers only require an
`@AutoConfigureWebGraphQlTest` to get a `WebGraphQlTester` component.
Closes gh-75
Prior to this commit, we could only test Spring GraphQL applications
with a complete application - all application and infrastructure
components were involved. While using `@SpringBootTest` is often useful
for complete integration tests (with or without a live running server),
we often want to write lean integration tests and test slices of our
application.
Just like `@WebMvcTest` or `@WebFluxTest`, this commit introduces the
support for `@GraphQlTest`. This annotation helps us to test a
particular slice of our application: a hand-picked selection of
`@Controller`, plus `RuntimeWiringConfigurer` and `WebInterceptor`
beans.
Other `@Component` must be imported or mocked for those tests.
This commit also refactors the existing auto-configuration to enable
this use case. The `WebGraphQlHandlerAutoConfiguration` now holds the
required components for `@GraphQlTest`, while other web-related
auto-configurations bring the web framework and transport
infrastructures.
Closes gh-75
As of gh-81, specific security components are contributed by the
GraphQL Security auto-configuration.
This commit removes those from the custom SecurityConfig classes.
The errorType field on GraphQLError is specific to GraphQL Java and when
serialized via GraphqlErrorHelper#toSpecification it becomes an
extension with the key "classification".
This commit ensures that we correctly deserialize back to errorType from
the "classification" extension but unfortunately that's limited to the
ErrorClassification enums that we know of.
This is unlikely to happen as authentication happens prior to reaching
the GraphQL APIs. However, a user may decide to implement security within
GraphQL as it is possible to do through a Spring Controller.
