CLOUDIFY-1839 Added filter to the rest-doclet request example generation process. Use this filter to decide for each parameter if it passed in the request body or not. Fixed the ApiVersionValidationAndRestResponseBuilderInterceptor.java to handle methods that returns String value.
CLOUDIFY-1839 back to only one interface to generate examples. does not support more than one parameter that is transformed in the request body. upgraded the restDoclet test.
CLOUDIFY-1828 Added rest client HTTP exception handler and fixed some check style issues.
CLOUDIFY-1882 Added RestConfiguration to the ServiceController.java so it will get the Cloud object from there. The rest temporary folder is also read from the RestConfiguration.
CLOUDIFY-1882 delete the rest temporary folder (if exist) before creating a new one.
