This commit changes the default location for the GraphQL schema from
`classpath:schema.graphqls` to `classpath:/graphql/schema.graphqls`.
We're also adding `.graphqlconfig` files that are leveraged by a GraphQL
JS plugin in IntelliJ IDEA.
Closes gh-44
This commit refactors the project structure to regroup GraphQL web
support under the spring-graphql-web module, and move all the Spring
Boot support classes under a single graphql-spring-boot-starter one.
Right now, the starter module contains everything: classes for MVC,
WebFlux and Actuator support as well as required dependencies. We will
change that in the future.
