CLI usability: jboss-admin needs to be able to authenticate users (using -u -p)

Only authenticated users can connect to the management interface (it's configured in the standalone.xml with security-realm="PropertiesMgmtSecurityRealm" in management-interface). This means, if you execute the above command it fails, because of missing authentication. In JBoss 6 that was possible with the arguments -u (user) and -p (password)

For instance if you want to run a script it says:

[rhusar@rhusar jboss-as-7.0.2.Final]$ bin/jboss-admin.sh -c --file=test.cli 
Authenticating against security realm: localhost.localdomain
The controller is not available at localhost:9999
You are disconnected at the moment. Type 'connect' to connect to the server or 'help' for the list of supported commands.
