This commit removes MediaType from the list of exclude types as it looks
like an error: MediaType has a constructor taking a `String` and binding
works fine with it.

This has the effect of properly generating the metadata for the only key
that Spring Boot exposes with a MediaType type:
spring.data.rest.default-media-type.

Closes gh-11568

This commit adds a javadoc note about a usability issue described in
gh-11255. While `RestTemplateBuilder` is an immutable class, providing a
custom instance of request factory and deriving several
builders/templates from that point may have some unexpected behavior,
since that instance is shared amongst builders instances.

This issue is fixed in Spring Boot 2.0 with a replacement method that
leverages a `Supplier<ClientHttpRequestFactory>` instead.
