ci: Cleanup kubevirt_vm integration test

- Use uniform way of naming plays, tasks and VMs
- Use uniform way of ordering task parameters
- Use defaults where possible
- Use CentOS 9 Stream instancetype and preference
- Generate SSH private key with empty password (-N "")
- Disable strict host key checking
- Add .gitignore for test files
- Fix skipping test key creation if already existent
