Active Record destroy async integration

Found out today about:

Destroy Associations Async
Destroy associations async adds the ability for applications to destroy associations in a background job. This can help you avoid timeouts and other performance issues in your application when destroying data. The implementation was a group effort - the PR was started by George Claghorn from Basecamp, further support added by Cory Gwin of GitHub and finalized by Rafael França and Adrianna Chang from Shopify.

The default job deletes in regular AR batches, the class called is configurable. It seems useful for this gem to provide a job that is interruptible and resumable.
