rustdesk: Initial deployment

Rust Desk is a remote assistance software solution.  The open source
edition is sufficient for what I want to do with it, namely: help Mom
and Dad troubleshoot issues on their PCs.  Mom is currently having
trouble with the Nextcloud sync client, so I need to be able to help her
with that.
