Merge lp:~barry/lazr.config/tox-fix into lp:lazr.config

[Barry Warsaw]

Fix Python 3.6 compatibility, and work around a problem with single-source bilingual namespace packages with dependencies in the same namespace.

2.2 (2017-02-07)
================
- Fix tox import failure related to https://github.com/tox-dev/tox/issues/453
  (LP: #1662701)
- Don't catch ImportErrors that might occur when importing lazr.config._config
  from lazr/config/__init__.py. It's unnecessary and masks legitimate
  ImportErrors of e.g. lazr.delegates.
- setup.py: nose is not an install_requires, so move this dependency to
  tox.ini. (LP: #1649726)
- tox.ini: Add the py36 environment and drop py32, py33. Ignore missing
  interpreters. Change to a temporary directory when running tox (to avoid
  the above tox bug). Invoke nose via -m instead of the mostly deprecated
  ``python setup.py`` approach.

Do a better job of isolation from cwd.

* Move the lazr subdirectory into src/
* Don't changedir in tox.ini.
* Add coverage as a dep to tox.ini
* Use python -s and nose -P for isolation.
* Adjust the doctest for compatibility of error strings between Python 2.7,
  3.5, and 3.6
* Add NEWS.

I like this change better.
