[PATCH v1 01/14] add function to copy NetworkManage connection profile to the initramfs

[Coiby Xu]

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.
