Add new tests checking the good behavior of the SMMUv3 protecting
2 virtio pci devices (block and net). We check the guest boots and
we are able to install a package. Different guest configs are tested:
standard, passthrough an strict=0. This is tested with both fedora 31 and
33. The former uses a 5.3 kernel without range invalidation whereas the
latter uses a 5.8 kernel that features range invalidation.

v3 -> v4:
- add tags for machine, distro in the class
- removed smp and memory overrides
- set default param value of common_vm_setup to False

v1 -> v2:
- removed ssh import
- combined add_command_args() and common_vm_setup()
- moved tags in class' docstring and added tags=arch:aarch64
- use self.get_default_kernel_params()
- added RIL tests with fed33 + introduce new tags

I tested it in a Fedora 32 aarch64 host. The execution output:

One thing that caught my attention was the amount of time spent on each 
test. It spend more than 2 minutes on the package installation 
(`self.ssh_command('dnf -y install numactl-devel')`) in the guest.

Without that operation, it runs way faster:

Install a package seems a good exerciser for disk I/O and networking, 
but maybe you can use another method for the sake of speed up the tests?

As discussed earlier with Cleber, I am aware the test duration is long
but it was useful finding bugs for SMMU with range invalidation. such a
bug could not be hit with a single boot + ping for instance.

Maybe we should have a mechanism that allows to put some tests out of
the automatic CI?

Thanks
