Compares the REST API reference to DXP config.

This tool helps to find missing REST routes, missing REST route methods and non-existent REST routes. It extracts reference routes from the HTML output of the raml2html build. It extracts configuration routes from the yaml files of the DXP. It compares routes existng only on one side and it compares methods of common routes. When a route doesn't exists on one side, it tries few argument renamings (like Id↔︎Identifier) or if the route if flagged (removed) (see #1642 for the unification of depreciation and removal flags).
