Add a CLI option to switch to fullscreen or maximize new or existing window

[joelday]

• Feature request
  Would like to have a CLI option to specify that any new instance/window is maximized/switched to fullscreen (depending on the OS). This would be convenient for a scenario in which (for macOS, for example) I want to launch from a shell script and have each window in its own space. (For macOS, I assume that the normally focused (last) instance will be switched to.)

If I can have an official opinion on what to call the CLI option, I'm happy to whip this up and do a PR.

Thanks!

@joelday how about having a setting that each new window opens as fullscreen? I am thinking to add this as part of the options for #10864

@bpasero, that would be awesome!

What about defaulting to Seirra's new native window tabs? :)

@joelday this landed in our insider builds (notes here). Maybe you give it a try and report back how it goes.

You can give our preview releases a try from: http://code.visualstudio.com/Download#insiders

Re Sierra tabs: this is #15478

This feature request will not be considered in the next 6-12 months roadmap and as such will be closed to keep the number of issues we have to maintain actionable. Thanks for understanding and happy coding!
