Move server_name/service_name in RegisterRosAction/RegisterRosService

[panwauu]

I think that the server_name and service_name bloats the behavior-tree and additionally add "ros logic" into the behavior-tree.
It would be more elegant in my opinion to add the server_name/service_name when registering the node.
I tried to make the change myself, but the nodes are always failing.
Can somebody help me with?

Thanks

I understand the fact that it add bloat, but I would rather keep two implementation (name as port or passed to the constructor).

To understand why your modified version don't work, you need to share a runnable example with me.

Good point to keep both options!
I started PR #16 to show my version.
