Commit Message

[pants_ng] Scaffolding for a pants_ng mode. (#23319)

In this mode the command line is parsed as an
NG invocation, and dispatched appropriately.

Of course at the moment there are no
implementations to dispatch to. That will follow.

This does expose a new option, `pants_ng` to users. 
There is a big warning not to set it, but we're not trying
to hide that we're working on a new thing, so I am
comfortable with this.
