[FEATURE]: Transition to ros2_control for controller interface

[evan-palmer]

Feature Type

Changing existing functionality in the BlueROV2 driver

Problem Description

The current implementation for developing and using custom controllers is custom, but still implements a structure similar to what one would expect within ros2_control. The main reason for the initial design is ultimately that I'm on a time crunch and didn't have the time to fidget with setting up the hardware interfaces and custom controllers.

Feature Description

Migrate the existing controller implementation over to ros2_control. This will improve the maintainability of the implementation and will also improve the integration of the project into the ROS ecosystem down the line (e.g., integrating MoveIt2).

Alternative Solutions

The existing approach could be preserved; however, I think that, if possible, it would ultimately be better to switch over to ros2_control.

Additional Context

I am not fully sold on migrating to ros2_control yet as that project is still working on maturing (at the time of writing, it is a massive pain in the butt to integrate ros2_control with Gazebo Garden). I'm also not sure whether the lifecycle node structure will apply super well when integrating with the manager or ArduSub. These are some things that will need to be considered when refactoring the architecture.
