Added the CYCLONEDDS.xml config to the Dockerfile, enabling multi-system ROS networks.

Possible Drawbacks

Need to tweak network buffer size on host kernel, using the following commands, otherwise messages will be lost.

# Increase the maximum receive buffer size for network packets
sudo sysctl -w net.core.rmem_max=2147483647  # 2 GiB, default is 208 KiB

# IP fragmentation settings
sudo sysctl -w net.ipv4.ipfrag_time=3  # in seconds, default is 30 s
sudo sysctl -w net.ipv4.ipfrag_high_thresh=134217728  # 128 MiB, default is 256 KiB
