[Java] Threetenbp dates support (#4029)

* [feign] add threetenbp support for feign clients

* [okhttp] add threetenbp support for okhttp clients

* [jersey] add threetenbp support for jersey clients

* [retrofit2] add threetenbp support for retrofit2 clients

* [spring] add threetenbp support for spring generators

* add a workaround in tests for a bug in the petstore
