> Currently, in {{TaskManager}} we don't distinguish between {{StreamTask}} and 
> {{StandbyTask}}. However, both have quite different live cycles and thus we 
> should try do distinguish between both.
> This also affect interface {{Task}} that should only contain method we need 
> for both type of tasks, but not contain sub type specific methods.
