Fix tox -e py34

* Add requirements-py3.txt: get the master branch of glance_store from
  github until a new release of glance_store including all my Python 3
  fixed will be released.
* Add test-requirements-py3.txt: remove qpid-python and MySQL-python
  (not compatible with Python 3), add PyMySQL
* tox.ini: add py34 test environment running tests with testtools.run.
  Use a whitelist of tests which are known to pass on Python 3.4. testr
  cannot be used because it loads all tests, and not all tests are
  compatible with Python 3.4 yet.
