Package python3-module-httpretty_fixtures: Information

This was written to solve communicating to an Elasticsearch during
tests. For our usage, mock didn't scale well and placing httpretty
fixtures on our base test case was impratical. To solve this, we wrote
a fixture manager, httpretty-fixtures.

Features:
* Reuse responses across tests
* Allows maintaining state between requests
  - See the Examples section for a demonstration
* Access past request information
  - On per-fixture basis
  - Across all fixtures
