Split framework dependencies from test dependencies.

Let separate test cases (tobiko.tests package) from framework
(the rest of tobiko).

- Move test case dependencies to test-requirements.txt file.
- Keep only requirements.txt as framework requirements file.
- Add python-networkclient dependency to tobiko framework
- update tox.ini to use it for checking code before committing it
