* Add Operating System developer documentation
This moves some of the existing documentation from the operating-system
repository, updates it to reflect the current state and extens certain
parts.
* Reword and add deployment documentation
* Add new pages to Sidebar
* Reword and extend various aspects
* Small fixes here and there
* Clarify builds
* Add information on turning off OS SSH access
The current documentation does not describe how to stop the SSH access to the host if it is no longer needed. The service will be stopped and the keys removed if the Home Assistant device is booted with an empty CONFIG drive inserted.
* Tweak

* Update OS debug example hostname
Updates the example given in debugging to reflect the default hostname. I use hostname as a term without explanation as anyone that doesn't understand the meaning shouldn't be using this doc (as stated at the top).
* Update note on different hostnames
