Add "expose" to "new createError.[code || name]([msg]))" syntax

[maneetgoyal]

Hi all,

Please consider add support for expose property in new createError.[code || name]([msg])) like syntax.

We use new createError.name([msg])) a lot because of its readability. It also mitigates the need to remember all those status codes. Being able to do something like below will be of great help.

var err = new createError.NotFound("Show this error to client.", {expose: true, ...});

Thanks for the suggestion @maneetgoyal . This will be included in the upcoming 3.0 release as it provides an update to align to the new options feature of the global Error constructor.
