Bug 1169939 - Tweak .landscape.yaml to improve signal to noise ratio

* Turns off warnings for tests (there are particularly noisy due to
  mocking - we can always turn this back on later).
* Ignores some files/folders that are either for third party code, or
  else don't play nicely with pylint/landscape.io (eg update.py, since
  commander isn't installed).
* Adds the prod.txt requirements file, so landscape.io can resolve the
  New Relic package references.
