network: update NM autoconnections configuration for centos

The policy should be the same for RHEL and CentOS Stream.
Apply also to rhel-like systems.

We can use systemd mechanism using triggering conditions either for
kernel option parsing or for system detection. It seems that systemd
would be better serving here for the kernel option conditions, os
detection seems to be more feasible on our side inside the service
execution script.

Resolves: RHEL-67815
