Provide module-scoped equivalents to @WebMvcTest and @DataJpaTest

With @WebMvcTest and @DataJpaTest we can easily create an ApplicationContext for the web- or data layer of our Spring Boot Application.

It would be nice to have equivalents to these annotations that only include the web- or data layer of our module under test into the ApplicationContext.

Same goes for the other annotations like @WebfluxTest, @JdbcTest and so on (see https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html).

Looks like @sbrannen was kind enough to add support for an escape hatch by adding an explicit annotation on the test class in Spring Framework 5.1.

Would you mind giving this another look on 5.1, @thombergs?

I just realized that the test works when I specify all three together

@ModuleTest
@SpringBootTest
@AutoConfigureMockMvc

But what does this mean for the bootsrapping? Does it initialize the whole application or only the current module?
