OPENDJ-3332 Rest2ldap: return the OpenAPI descriptors over REST

Follow up of CHF-135 "Api descriptor requests (?_api) cannot be proxified".
This change allows to query OpenAPI descriptions by using the "_api" query parameter.

Add the OpenApiRequestFilter to the filter chains to handle requests using the "_api" query parameter.
