Consistent behavior for Subordinate nodes
"""""""""""""""""""""""""""""""""""""""""

Inconsistent behavior of subordinate nodes was fixed.
The subordinate node is a secondary node associated with a primary node, that shares the same underlying context and resources while maintaining a separate name and namespace.
The behavioral modification may affect existing applications relying on the previous implementation:

1. Generic clients created from a subordinate node now correctly respect the subordinate node's sub-namespace
2. Parameters obtained using a subordinate node now correctly use the (parent) node's ``rclcpp::node_interfaces::NodeParametersInterface``

See https://github.com/ros2/rclcpp/pull/2822 for more details.
