Issue #2462
Description of changes:
Raw builds are run on KVM vms. RHEL 8.x ships with dracut that builds initramfs with default host-only mode set to true. This causes the initramfs to only include drivers that are required to run kvm infrastructure. When the disks are exported and booted on a metal server, the OS fails to boot up due to this missing drivers.
This change runs dracut with --no-hostonly to rebuild initramfs to include all drivers
This PR also fixes another issue that bubbled up during testing the dracut changes. The build_type was not set to raw in the rhel json file, causing providers role to run qemu tasks as opposed to raw tasks.
