[PATCH v2 02/47] add lnst.Common.DeviceError

From: Ondrej Lichtner <olichtne(a)redhat.com&gt;

Defines some basic Exceptions signaling some error with a Device object
(to be added in a later commit). Since these Exceptions can be
transmitted to the Controller, they need to be in the Common package.
