Adding parameter-based ability to resolve expressions via management API and CLI commands

https://issues.jboss.org/browse/WFLY-1069
Here super.recognizeArguments(ctx) should still be called, this is what will validate other arguments present on the command line.
Then, I'd suggest to first check whether resolve.isPresent(parsedCmd) is true and if so then check whether it's actually allowed for the given path, otherwise read-operation-description will be executed for every entered ls even if the user didn't ask to resolve expressions. (The same for the ReadAttributeHandler)
