Items to finish before Jazzy release

[clalancette]

This issue puts together the list of items, in rough priority order, that should be completed on rmw_zenoh_cpp before Jazzy. Not all of these are strictly required, as basic functionality is already there, but having all of these will go a long way towards making rmw_zenoh_cpp something that people can actively try out.

Status	Item	Why?	Related issues/PRs
Complete	Events support	Required for rviz2, ros2 topic, and other tools	#103
Complete	Build rmw_zenoh_cpp on Ubuntu 24.04 with rustc on that OS	Will be necessary to tell users how to use rmw_zenoh	#136
Complete	Implement rmw_take_serialized_message{_with_info}	Required for rosbag2	#113
Complete	Implement rmw_get_gid_for_client	Required to support service introspection	#115
Complete	Implement rmw_get_gid_for_publisher	We are currently lying to the upper levels, so should fix that	#116
Not started	Implement rmw_publisher_wait_for_all_acked	Required to support rclcpp/rclpy wait_for_all_acked, used in tests
Complete	Allow the user to pass a custom config file to init_rmw_zenoh_router	User customization of zenohd will be important	#119
Complete	Fill in the source timestamp and GID for published messages	End-users expect this information to be there	#123
Not started	Restrict Zenoh sessions/router to a specific network interface	Important for certain use cases, like Velodyne sensors which use ethernet
Complete	Run rmw_zenoh_cpp against all tests in the ROS 2 core	This will give us much more confidence in the things we have implemented, and show us weaknesses	#162, #161, #156, #154, #151
In progress	Revisit how and when to start the zenoh router; should we do it all, should we do it automatically, or should we make the user do it?	Starting it automatically makes it more seamless, but gives the user less opportunity to configure. Need to consider the tradeoffs and what the default should be
