Previously, if multiple WebHandler beans were present, the auto-config
for WebTestClient fail to identify a suitable candidate as it expects
to only have such a bean.
This commit updates the logic to look for a well-known bean name that
WebFlux uses, and clarify the exception message to state that a bean
with a given name is expected to be found.
The exception message has been further refined to mention that, if
such a bean is not present, then a MockMVc-compatible ApplicationContext
should be available (i.e. WebApplicationContext).
Closes gh-47617
Create `spring-boot-resttestclient` and `spring-boot-webtestclient`
modules to hold test client auto-configuration and `TestRestTemplate`
code.
Previous these classes were contained in `spring-boot-resetclient-test`
and `spring-boot-webclient-test` which was incorrect since the `-test`
modules should hold code need to test the given modules, not supporting
test classes.
