Java support for application/xml (#5962)

* WIP: CodegenProperty with XML

* WIP: CodegenModel XML bits

* WIP: Jackson XML

* WIP: Java templating

* WIP: Java client withXml flag

* WIP: resttemplate work

* WIP: withXml only when Jackson is used

* WIP: Tabs to spaces

* WIP: java-petstore-resttemplate-withxml sample

* WIP: language: spring

* WIP: language "spring" using library "spring-boot" should include apiPackage in @ComponentScan to detect the API

* WIP: javax.xml for non-Jackson Java and enabled payload logging for jersey2

* WIP: updated java petstore samples

* WIP: JavaSpring with non-jackson XML

* WIP: bin/spring-all-pestore.sh
