Add pep8, pyflakes, unit and integration tests to setup.py

[diranged]

Bump nd_service_registry to 0.3.0a1. Adds the following cleanup items:

1. Pep8, Pyflakes, Unit and Integration Tests to setup.py
2. Documentation cleanup
3. Make TravisCI execute pep8, pyflakes and unit tests through setup.py
4. Document how to use Vagrant to run integration tests

[diranged]

The pep8/pyflakes requirements are put into requirements.test.txt in https://github.com/diranged/ndserviceregistry/commit/2a6772d9eae5054772f4015f75f5782fc3257fbd

I am a little wary when I see statement like except Exception:
We should be more specific on what exception to accept.

Spoke to Matt about this. He is going to insert the TODO to work on that on later days.
Once that's done, this change is approved.
