[sudo-sys] Changes to saros

Jake is getting a lot of access requests for the omni door and wanted to be able to activate the door from a web page with simple authentication, so I've made the following changes to saros. 1. Enabled CGI scripts behind https & basic auth. 2. Added a script that opens the door. 3. Compiled and installed python-3.9 in /opt because the current debian distro is out of date. 4. Edited the firewall rules to allow mDNS, and to allow the esphome port. I made a commit to the firewall rules git repo. I realize CGI scripts were probably turned off on the router on purpose, and my preference would be to proxy to another host that handles the door stuff. But it's my understanding there's no suitable machine available. Alex
