> We need a general solution. A change to the stack definition to capture
> package requirements that are optional and config dependent. Something in the
> line of:
>   * additional package - pkg_a
>   * install if params.install_pkg_a is true
>   * install_pkg_a is true if (some custom service specific condition is true)
>   * both install() and start() commands need to check if install_pkg_a is 
> true and then install the package (or remove from excluded package)
>   * by default all additional packages are exluded
