Add accessor methods WebClient.getBaseUrl() and RestClient.getBaseUrl() about spring-framework

[snicoll]

@honza-zidek I am not sure I am following, what is the use case?

[honza-zidek]

@snicoll A possible use case is e.g. in testing. Wherever you want to be sure which base URL has been actually set for a specific client.

I can't see any reason why, when the base URL is set in the implementation agnostic builder, the interface is missing a method to get the value, and you have to use reflexion.

If the use case is testing, then we're going to decline this enhancement request: you shouldn't test Spring Framework's code and if anything, you should test that the client generates URLs with the configured base.

Also, in the case of WebClient, that information is lost as the base URL is turned into a UriBuilderFactory, which is much more than a base URL. Same applies to RestClient. So even if we agreed to, there is no easy way to implement the feature you're asking for. I'm closing this issue as a result. Thanks!
