[jboss-as7-dev] importance of model descriptions and request validation

We don't validate request properties on the server side. Not in general, at least. It's a responsibility of handler implementations that, in a good case, validate only property values. There were complains from CLI users about the fact that unsupported properties in requests (put by mistake) were simply ignored w/o a warning. I think it makes sense to fix it in a general way on the server side. Anyway, I added validation in the CLI based on the model description. So now, of course, if a model description is incomplete, the CLI won't allow an operation request which is actually correct. Here is one example AS7-2432 CLI does not allow a new security-realm to be defined within the management section of a host Alexey
