Hirefire-resource

* Mitigate issue where measuring the Celery job queue size and job queue latency results in connection reset errors. If a connection is reset, the macro will attempt to reconnect and retry the operation up to 10 times over a span of 10 seconds before giving up. The ConnectionResetError typically resolves after the initial reconnection attempt, so this should help alleviate the issue.

* Fix issue where Django's HttpResponse object doesn't accept the headers keyword argument. Headers are now applied to the response object directly.

* Add support for dashes in `Worker` names to match the Procfile process naming format. `Worker` is implicitly used when configuring HireFire using the `Configurationdyno` method.

* Initial release.
