Code review comment for ~ma-brothier/cloud-init:interfaces-order

Marc,

This looks good. Some comments... they're all minor, and should be explained more in HACKING.rst
http://cloudinit.readthedocs.io/en/latest/topics/hacking.html

a.) change description to be
    Summary
    <blank line>
    Description

b.) lets go ahead and just keep the function in a net/__init__.py rather than putting it in util. And name it _natural_sort_key(). At some point if someone else needs such a function we can move it to util.

c.) a unit test would be good. Just add something to tests/unittests/test_net.py to test your _natural_key_sort. Also realize you can (and do) get interfaces named 'enp0s25' (as I have on this system).

d.) You'll need to sign the contributors agreement (see HACKING.rst). Please feel free to ping me if you have any questions.

e.) Thanks!

d.) Thanks!
