* Start work on supporting rfc7807 errors in REST API v3

* Completed the separation of exception mappers for the different APIs (core v3, core v2, ccompat)

* Switch from Error to ProblemDetails in Core v3 API + update all tests

* updated the UI to support the new problem format

* Code formatting
