Add ability to specify custom python requirements.

This lets you specify additional python packages to be installed
into the edxapp virtual environment.

The `EDXAPP_EXTRA_REQUIREMENTS` should be a list of dict objects
with `name`, `version` (optional) and `extra_args` (optional) keys,
that correspond to the options of ansible's pip module.

Example:

    EDXAPP_EXTRA_REQUIREMENTS:
      - name: mypackage
        version: 1.0.1
      - name: git+https://git.myproject.org/MyProject#egg=MyProject

TE-414: packer jenkins_worker: use ansible 1.7.1 for testing build server.

The test_build_server role was failing on acceptance tests because of unicode
static assets being gathered in collectstatic for django. This was because of
this issue https://github.com/ansible/ansible/issues/6655, which has been
resolved in recent ansible versions. We must override the version that is
being used by this repo, and upgrade ansible at provisioning time for
running the test_build_server role.
