ironic-lib is being retired; this change imports any used code from ironic-lib and updates references. This contains some changes to how we throw exceptions; aligning ironic-lib code with IPA practice to have all exceptions be a RESTError. This also allows us to remove code around serializing ironic-lib exceptions. Change-Id: I137340ce6820c68d8e0f1a32668151bba7b1ddd7
