[PATCH 1/2] node_device_udev: handle move events

[Mark Asselstine]

It is possible and common to rename some devices, this is especially
true for ethernet devices such as veth pairs.

In the udevEventHandleThread() we will be notified of this change but
currently we only process "add", "change" and "remove"
events. Renaming a device such as above results in a "move" event, not
a "remove" followed by and "add" or vise versa. This change will add
the new/destination device to our records but unfortunately there is
no usable mechanism to identify the old/source device to remove it
from the records. So this is admittedly only a partial fix.
