Assume yes option for stop, unpack, emptydb, restoredb.

The -y, --yes, --assume-yes option will happily cause the commands
mentioned above to be executed without asking for confirmation.

Instead if starting a new python program and importing the m2ee library,
some customers try to automate their deployment using a shell script
invoking the m2ee CLI command. While the CLI program is meant to be used
interactively, it's an accessible way of starting to do some automation.

Keep in mind that this option will only automatically answer some yes /
no questions. It will not handle more difficult issues like not being
able to start an application because there's a user with admin user role
and password '1', etc.
