Kvm test

[Yarboa]

Adding KVM tier-0 rpm subpackage testing

KVM tier-0 tests dedicated for kvm tests.
It checks /dev/kvm. nested virtualization exist.
In case not, it removes qm_mount_bind_kvm rpm, in case installed by packit.

Test check_qm_setup_succeeds is the irst test to run,
The test check repo setup script is working properly

Packit support for nested kvm support added currently for fedora/c9s
Kvm tests should be introduced later.
Introducing QM quadlets drop-ins for extending qm.container base quadlet.
Using as single point of configuration.
Replacing the usage of containers.conf

Fedora is failing due to #666

@dougsland
caught the following selinux error causing QM restarts on fedora, need to check for c9s

vda4.txt

It is very interesting, in fedora once adding the following file to for exposing /dev/kvm
/etc/qm/containers/containers.conf.d/qm_dropin_mount_bind_kvm.conf

# Drop-in configuration for Podman to mount bind /dev/kvm from host to container
#
[containers]
devices = [
	"/dev/kvm:/dev/kvm",
	"/dev/net/tun:/dev/net/tun"
]

@rhatdan any inputs are welcome

Indeed, we are exposing /dev/kvm and also /dev/net/tun which was required during my tests.
@Yarboa , It should be automatically by the subpackage. Isn't working ?

For the future as reference:

/dev/net/tun represents a TUN (network tunnel) device in Linux systems. It is used for network tunneling and is a part of the TUN/TAP driver that allows for virtual network kernel interfaces. KVM can use /dev/net/tun when setting up networking for virtual machines (VMs). Specifically, it is utilized when creating a network bridge or using a TAP (network tap) device to provide networking for VMs. (During my tests I noticed this).

@rhatdan any inputs are welcome

Failing gate is f41
please refer this WIP issue
It is generic problem with fedora, currently blocked on that
