Improvements to nexus_network_configuration

[Yadunund]

• Update to Zenoh 1.0.0 and switch to zenoh-plugin-ros2dds
• Consider dropping nexus_zenoh_bridge_dds_vendor since the newer bridge is also distributed through the ROS buildfarm
• Get the allowed endpoints from nexus_endpoints.redf.yaml. Presently the endpoints are hardcoded in configs

  add_allowed_endpoints: ["/list_workcells", "/.*/workcell_state", "/.*/is_task_doable", "/.*/request", "/.*/queue_task", "/.*/remove_pending_task", "/register_workcell", "/register_transporter", ".*/available", ".*/transport", "/estop", "/.*/pause", "/.*/get_state", "/.*/change_state", "/.*/signal"]

• Upgrade setup_network.py to retrieve ROS distro from envar before installing rmw_cyclonedds_cpp

I looked at the distributed packages and, apart from the fact they have been failing for some time, it seems the only distributed package is zenoh_bridge_dds and at version 0.5.0.
With this in mind I assume it's not possible to use the binary package unless they start to distribute the ros2dds bridge and bump it to 1.0.0?
