Some systemd-based systems (e.g. RHEL7) have moved to "predictable network interface names" which are designed to remain consistent as new interfaces are added or removed from a system. Alas, that means these systems end up with a complex patchwork of potential new interface names. This patch implements the "spec" as defined in the header of https://github.com/systemd/systemd/blob/master/src/udev/udev-builtin-net_id.c See also https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/

This patch allows these "new" interface names to actually generate tcollector output.

The regex for interface names is now big and ugly, which is mitigated by using a multi-line "verbose" regex. Suggested improvements for the format of this regex welcomed.
