CI: implement GitHub Action to test AlmaLinux x86_64 distribution

- test on VM managed by Vagrant and on libvirt provider
- add Vagrantfile for AlmaLinux
- support of pungi yum repository (with almaLinux upcoming version packages)
- support of pulp yum repository (with almaLinux build system packages)
