Add support for Spring's RestTemplate in Java client codegen (#5404)

Browse Source 
* Add support for Spring's RestTemplate in Java client codegen

Resolves #1176

* Update all Java samples to include change for Jackson enums

Currently enums are deserialized from a String value with an
explicit @JsonCreator. However, they are not being serialized with
this String value. This change introduces the @JsonValue annotation
on the toString() method of enums, so they will be serialized as a
String with the correct value.
