> It makes more sense to return port resource for a given role, rather than all ports in Resources.
> In mesos/resource.hpp:
> Option<Value::Ranges> Resources::ports(const string& role = "*");
> // Check whether Resources have the given number (num_port) of ports, and return the begin number of the port range.
> Option<long> Resources::getPorts(long num_port, const string& role = "*");
