Botocore and the replacement for unixsocket have an unavoidable dependency conflict for Python 3.9. Options for resolving this are to drop support for Python 3.9, freeze requests/urllib/requests-unixsocket at their current version, or replace requests-unixsocket with something else

I'd vote to drop support for Unix Sockets. Originally I was thinking that this might be a performance enhancement for clients and servers on the same host, but it's marginal if anything. Also, I think there can be problems when two clients are using the same socket connection.

If we go this way, the ruanll.sh script should change the --no-docker option to use TCP rather than sockets.

Actually we use unix sockets in hsds_app.py, and I prefer not to update the code to use tcp sockets.
Let's go with changing the unix-socket to use the gitlab project.

Let's go with this. I'll submit a PR to remove Python 3.9 support
