[wildfly-dev] Change CLI to Default to Remoting

[Darran Lofthouse]

Access control did take priority for a while, anyway back on clearing 
out some tasks for WildFly now so this one has popped up again with some 
other related issues.

I have put together a small article here on how we should handle 
addresses, especially addresses that are not complete here: -

https://community.jboss.org/wiki/CLIConnections-AddressHandling

The last time this was discussed one concern was if we wanted to drive 
the port number from the protocol this didn't cover the scenario where 
users are used to 'localhost:9999' - this is covered by defining an 
alias to map that address.

Regards,
Darran Lofthouse.
