Use boto 2.32.1
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
Don't restart edxapp after updating on devstack

Added Brandon DeRosier to authors
remote maintenance site.
Operationalize harprofiler.
Add s3 watcher plugin.

Here is an example vars.yml file to pass in when running the newrelic role
with s3watcher enabled:

  ---
      S3_ACCESS_KEY_ID: s3accesskeyid
      S3_SECRET_ACCESS_KEY: s3secretkey
      S3_BUCKET_NAME: bucketname
      AWS_REGION: us-foo-1
      S3_CONFIG_FILENAME: fooconfigfile
      NEWRELIC_S3_WATCHER: True
      NEWRELIC_LOGWATCH: False <--not a required var, but it's True by default
      NEWRELIC_LICENSE_KEY: "my_api_key"
adding override for OAUTH_ENFORCE_SECURE
move venv to subdir and activate it.
disable S3 watcher by default
Harprofiler repo is now under edx. Disable test cruft.

The test was under dev and shouldn't have been merged. (This
approach is incompatible with ansible's design.)
