Support for Ubuntu 21.10 Impish Indri

[LouisMT]

Please add support for Ubuntu 21.10. It will be release on October 14.

Also see #940 and #832. I'm opening the new issue because the first one seems a bit stale.

Thanks.

Before merging docker/docker-ce-packaging#585, they will probably need to upgrade their CI/CD infrastructure to Docker v20.10.10 or later, because Dockerfile with FROM ubuntu:21.10 cannot be built with Docker prior to v20.10.10.

Docker 20.10.10 is not released yet, but will be released very soon: moby/moby#42836 (comment)

Yes, this is a bit of a chicken-and-egg situation; I started a test-build for 20.10.10, and if all goes well, planning to publish packages for an rc1 to our package repositories, and update our CI nodes to use that.
