Support WebTestClient in AutoConfigureRestDocs

[zaynetro]

At the moment @AutoConfigureRestDocs only supports Mock MVC and REST Assured. It would be nice to have WebTestClient (webflux) support there too.

Spring boot version: v2.0.6.M6

I am willing to take a look at resolving this if someone is willing to guide me through the process.

If I understand correctly I may simply add the similar conditional static class as in (https://github.com/spring-projects/spring-boot/blob/master/spring-boot-project/spring-boot-test-autoconfigure/src/main/java/org/springframework/boot/test/autoconfigure/restdocs/RestDocsAutoConfiguration.java) but for web test client configuration (https://docs.spring.io/spring-restdocs/docs/2.0.0.RC1/api/org/springframework/restdocs/webtestclient/package-summary.html).

Plus create config customizer similar to https://github.com/spring-projects/spring-boot/blob/master/spring-boot-project/spring-boot-test-autoconfigure/src/main/java/org/springframework/boot/test/autoconfigure/restdocs/RestDocsMockMvcConfigurationCustomizer.java

The question then is where should I place a test for this new configuration option?

OK. Tests go to https://github.com/spring-projects/spring-boot/tree/master/spring-boot-project/spring-boot-test-autoconfigure/src/test/java/org/springframework/boot/test/autoconfigure/restdocs

Am I on the right track?
