Please backport python-xmltodict 0.9.2-3 (universe) from wily

[Sebastien Badia]

Please backport python-xmltodict 0.9.2-3 (universe) from wily to trusty (and vivid, if possible).

Reason for the backport:
========================
NEW package in trusty, and needed by OpenStack https://review.openstack.org/#/c/286316/

Testing:
========
Mark off items in the checklist [X] as you test them, but please leave the checklist so that backporters can quickly evaluate the state of testing.

You can test-build the backport in your PPA with backportpackage:
$ backportpackage -u ppa:<lp username>/<ppa name> -s wily -d trusty python-xmltodict

* trusty:
[ x] Package builds without modification
[ x] python-xmltodict installs cleanly and runs

* vivid:
[ x] Package builds without modification
[ x] python-xmltodict installs cleanly and runs

Thanks in advance!
