Fix required attributes when error happened
Accroding to the NFV-SOL 013v2.6.1 Section 6, modify the API's response body format when error happened. Add title, status and detail attributes and delete problem type, code and message attributes in the response body when error happened. And also change the "Content-Type" from "application/json" to "application/problem+json". Closes-Bug: #1930647 Change-Id: Ic5f08ca924d14a382baeb77470aa3430e317315f
