Agent v3. Doc Feedback

[mjang]

Describe the bug

• While at the moment NIM supports agent v2 and N1C works with both v2 and v3, it's kind of confusing to see that v3 docs are not here https://docs.nginx.com/nginx-agent/ but https://docs.nginx.com/nginx-one/agent/

  • I presume that when NIM supports v3 those pages will be moved under the main Agent tile but I wonder whether it would make sense to keep everything under the agent adding a simple compatibility matrix showing what agent version is supported by either control plane

• here https://docs.nginx.com/nginx-one/agent/configure-instances/configuration-overview/ it would be great to add more context for NGINX_AGENT_LABELS

  • as there is no mention on how to set the Config Sync Group and what separator has to be used for each key-value pair (it might be a semicolon, an equals sign etc).
  • Adding an example such as --labels "config-sync-group=,extralabel=value,..." might definitely help

I think the plan is to add the relevant docs under NIM
