Consider changing the default CLI connection

[macjuul]

When using the CLI you would expect the surreal sql command to connect to the database started with surreal start using the default port, however currently you must always specify the localhost URL as the default is set to the surreal cloud URL, which at this point does not resolve to anything yet. This same seems to apply to surreal export as well.

It makes more sense and is more user friendly if the default connection is set to http://localhost:8000.

Additionally another option would be to introduce a command to set the default connection.
