override property to bypass prompt. #6

Although prompting is a good UX for first time users, power users may prefer passing in all the options as cli arguments.

I propose adding prompt.override which could be used to achive this:

prompt.override = {name: 'whoever'}

prompt.get(['name'], function (err,answer){
   //it will just take name from .override and not prompt the user. 

Then it would be a one line change to add this feature to all the nodejitsu cli tools, prompt.override = optimist.argv

the option would still be validated, and would call back an error if it failed.

it's certainly possible. but I don't think there are currently any collisions in the nodejitsu cli tools.

can you think of any?

My first intuition is that you could easily get around needing this by doing something like:

    (function (cb) {
        if ( {
        } else {
            prompt.get(['name'], cb);
    })(function(err, name) {
        //. . .

...but then I realize that, despite having mixed feelings about the prompt.override interface a'priori, it'd certainly be cleaner than having no way to avoid the text mess above.
