Currently when an error code is returned from any of EJBCA's servlets (OcspServlet, CmpServlet) to CLI clients such as clientToolBox and cmpClient, only the error code is printed out with no further information.
The servlets themselves provide proper messages in the responses.
For better usability we should print out the error code along with the actual message. E.g. 403 - CMP is disabled (which might be returned from the servlet).
