pythonPackages.beaker: 1.8.0 -> 1.10.1
pythonPackages.beaker: 1.8.0 -> 1.10.1

- The aim was to get this building on hydra
- Midway I discovered a PR by Mic92 that bumps the version to 1.10.0,
  I have included some of his fixes to run tests correctly:
    - remove testing memcached (it tries to connect on import)
    - don't run external tests or a failing test on darwin
            (see https://github.com/bbangert/beaker/issues/166)
    - run nosetests rather than setup.py test because we need to specify
    exclude options.
