> In the stack definition if a property of service component is not defined in
> one specific version than it will be inherited from the parent version.
> The `ComponentInfo.cardinality` always has a default value of "0+" from the
> moment the object is instantiated thus the inheritance logic is never applied.
> This leads to if a specific version of a service component doesn't have a
> property set in stack definition it won't inherit it from its parent but
> rather will take the "0+" default value.
> This is not the correct behaviour. First the inheritance should be applied and
> only set `cardinality` to "0+" only if it can't be inherited from the parents
> (as it's not defined in any of the parents up in the inheritance chain)
