Support ROS_AUTOMATIC_DISCOVERY_RANGE and ROS_STATIC_PEERS

[evshary]

Describe the feature

Based on the description on the description of Dynamic Discovery, we might need to make some apropriate changes.
https://docs.ros.org/en/rolling/Tutorials/Advanced/Improved-Dynamic-Discovery.html#id4

1. ROS_LOCALHOST_ONLY will be deprecated in the future, but to ensure the backward compatibility, --ros-localhost-only should be kept and perhaps show warning to users if they are using ROS 2 Iron or later.
2. Now we have both ROS_AUTOMATIC_DISCOVERY_RANGE and ROS_STATIC_PEERS environmental variables and will affect the DDS configuration. We might also need to support these two arguments --ros-automatic-discovery-range and --ros-static-peers.

@JEnoch I would like to know your thoughts about this.

We can refer to rmw_cyclonedds_cpp for the DDS configuration.

@JEnoch, since we agreed on the proposal during the meeting, I will start implementing it.

Implemented in #334 .
