Description

Currently the error/exception messages are hand constructed all over the Atlas code base, making it hard to understand the origin of the problem. Also since Atlas is moving towards a more RESTful nature it's better to create a catalog for the error message with support for localization

Proposal:

Format:
internal_error_code=external_error_code|error_description
internal_error_code_status=http_status_code

e.g.
entity_not_found=entity_not_found|Given entity doesn't exist
entity_not_found_status=404
