A BT port is introduced in case the user wants to change the default action_name
of BtActionNode.

- `BtServiceNode::check_future()` was created, to encapsulate the logic
where a the output of the BtServiceNode is computed.
- Inherited classes can overload this function according to the requirement
of the user

* Proposed refactoring to avoid issues with CoroAction

* correctly haltAllActions (related to #1600)

* not really needed and will be deprecated soon

* Applying changes suggested in the comments of #1606

- fix haltAllActions
- changes method signature on_success()
- reverts the changes made here:

In general, you never set your status to IDLE, unless halted.
