ZTS: Use QEMU for tests on Linux and FreeBSD
Browse files Browse the repository at this point in the history 
-----------------------------------------------------------------
Do not merge - this is my testing version
-Tony Hutter

Requires-builders: none
----------------------------------------------------------------

This commit adds functional tests for these systems:
- AlmaLinux 8, AlmaLinux 9
- ArchLinux
- CentOS Stream 8, CentOS Stream 9
- Fedora 38, Fedora 39
- Debian 11, Debian 12
- FreeBSD 13, FreeBSD 14, FreeBSD 15
- Ubuntu 22.04, Ubuntu 24.04

Workflow for each operating system:
- install QEMU on the github runner
- download cloud image for this system
- start and init that image via cloud-init
- install deps, build openzfs, load the module
- do the functional testings, hopefully < 5h
