Code review comment for lp:~robertcarr/mir/rebuild-input-focus-selection

I think we need to start thinking about adding structure to the DisplayServerConfiguration hierarchy.

For example:

class DisplayServerConfiguration ...

class InputConfiguration ...

class DefaultInputConfiguration : public virtual InputConfiguration ...

class DefaultDisplayServerConfiguration :
    public DisplayServerConfiguration, public virtual InputConfiguration,
    private DefaultInputConfiguration ...

Maybe not for this MP, but I we should be able to break things into functional areas.
