Create a {{gen2local}} gen2Actor configuration

We currently have g2real and g2sim configurations for the gen2Actor. The only real difference between them is the Subaru hostname which we connect to.

We also want a gen2 configuration for running disconnected. Tests suggest that we can actually run the same core program and ignore errors about connection errors. Flesh that out.

Of course, we will need to fake up OBCP status keys and the visit sequence. The former is easy, the latter could get messy.

Call it g2local.
