Call `self._http.close()`, since `google_auth_httplib2.AuthorizedHttp` (googleapis/google-auth-library-python-httplib2@feda187) has been fixed to also have a `close` method like `httplib2.Http()`


Fixes #1046 🦕

Fixes #1240 🦕

Update README to promote [cloud client libraries](https://github.com/googleapis/google-cloud-python) for new code development for the following reasons:
- There is a separate client library for each API, so you can choose
which client libraries to download. Whereas, `google-api-python-client` is a
single client library for all APIs. As a result, the total package size for
`google-api-python-client` exceeds 50MB.
- There are stricter controls for breaking changes to the underlying APIs
as each client library is focused on a specific API.
- There are more features in these Cloud Client Libraries as each library is
focused on a specific API, and in some cases, the libraries are owned by team
who specialized in that API.
- Developers will benefit from intellisense.
