Title: Support for Hosted Graphite API Keys

Hosted Graphite requires one to submit carbon metrics prepended with an API key. For example, the metric `foo.bar` would be submitted as `12345.foo.bar`.

This changeset includes the appropriate code, specs and README updates.

To use an API key, one just configures the `API_KEY` environment variable appropriately.

This has been tested on Heroku.
