Each network interface is manged by a NM connection. Given a network
interface name, this function will be used to copy a NetworkManager (NM)
connection profile i.e. a .nmconnection file to the kdump initramfs.

in the end this function gets quite large and (at least for me as a
network simpleton) quite hard to read. Is there a way to split it up in
multiple functions?

nmcli has the -t, --terse option to suppress printing of the header
line.
