Create InMemoryReactiveClientRegistrationRepository in web-application-type=none

[rwinch]

Currently Spring Boot only creates InMemoryReactiveClientRegistrationRepository in web applications. However, it is quite likely that users will want to leverage this with non web applications (i.e. a CLI tool).

It would be nice if InMemoryReactiveClientRegistrationRepository would be created for non web applications too.

We also need to create a ServerOAuth2AuthorizedClientRepository bean.

Thanks! I can confirm that this is working and improves the setup for those using a non-web application. You can find the diff after these changes here rwinch/webclientoauth2-cli@ed86aed
