Subject: [PATCH] Adds argument to disable opening all apps on startup

When --open=false is passed the Angular CLI won't open a new browser tab for each app that was started.
If the argument is not passed the Angular CLI will open a new browser tab for each app that was started, to not break the current flow for users

The implementation of yargs could be considered to allow a simpler/cleaner way of implementing more arguments in the future
