Any plan to mirror the Deadline installers to other aws partitions?

The Deadline installers and Docker recipes are currently published to an S3 bucket that exists in the main aws partition. These are not accessible to the China or GovCloud regions. We also need to investigate whether other functional parts of RFDK will work in these partitions.

We would like to eventually support other AWS partitions, but at the current time we are focused on providing more core functionality to the RFDK. We will keep track this request in our backlog and hope to pick this up in the future
