Merge lp:~xnox/ubuntu-dev-tools/py3k into lp:~ubuntu-dev/ubuntu-dev-tools/trunk

[Dimitri John Ledkov]

Port ubuntutools module & test suite to python3.

[lp:~xnox/ubuntu-dev-tools/py3k]

1423. By Dimitri John Ledkov on 2014-12-19

There is no python3-soappy yet.

1424. By Dimitri John Ledkov on 2014-12-19

Mock mock more.

[Dimitri John Ledkov (xnox)]

I am pondering to land this in vivid (it will take time to go through new) and then make the library available and then continue to port the scripts.
