bodhi REST API client

This package contains WIP rust bindings for the [bodhi] REST API.

It uses the awesome reqwest and serde packages.

Current status

• All GET requests are implemented, and all actual API responses should successfully deserialize.
• No POST requests are implemented yet, because
• OpenID authentication is not yet implemented.

Note that the API is not finalized yet, and minor changes will still happen before the 0.1.0 release.
