allocator template example in rclcpp

	template<typename MessageT, template<typename> class Alloc = std::allocator>
	class Publisher : public PublisherBase
	{
	// ...
	Alloc<MessageT> message_allocator_;
	// Publisher doesn't have any STL structures, but suppose it did (or think about the case for services):
	std::vector<AnotherType, Alloc<AnotherType>> my_vector_;
	// ...
	void my_function() {
	// instead of MessageT * msg = new MessageT;
