Introduce stack setup script

Introduce stack setup script

This change introduces setup-stack.sh script which will do setup
for the stack itself such as setting the default scenario if not
specified by the user and more importantly installing the dependencies.

Further changes will be sent, moving dependencies to stacks and
installations of those into stack setup script.
