Disable History

[nixpulvis]

It's unclear how to disable History if it's even possible.

Furthermore the docs for Reedline::create state: "Create a new Reedline engine with a local History that is not synchronized to a file.", however looking at the implementation it is set to aFileBackedHistory. This seems like another issue.

In nushell, I think we set history max_size to 0.

This indeed works:

.with_history(Box::new(FileBackedHistory::new(0).unwrap()))

Though it would really be nice to do something like .with_history(None) or .disable_history().
