Expanded tests on signals_test.go to cover more lines of code. 'go test' won't show 100% coverage (only 66.7%), because one test need to spawn a new
process (since it is testing a function that calls os.Exit(1)).

This patch adds keep_abnormal in runtime config. If keep_abnormal =
true, it means that 1) if the runtime exits abnormally, the cleanup
process will be skipped, and 2) the runtime will not exit even if the
health check fails.
This option is typically used to retain abnormal information for
debugging and should NOT be enabled by default.

Never ever try to close the same fd double times, even in a unit test.
A file descriptor is a number which will be reused, so when you close
the same number twice you may close another file descriptor in the second
time and then there will be an error 'Bad file descriptor (os error 9)'
while the wrongly closed fd is being used.

On some systems a GPU is in a IOMMU group with a PCI Bridge and
PCI Host Bridge. Per default no PCI Bridge needs to be passed-through.
When scanning the IOMMU group, ignore devices with a 0x60 class ID prefix.

When testing on AKS, we've been hitting the dial_timeout every now and
then. Let's increase it to 45 seconds (instead of 30) for all the VMMs,
and to 60 seconfs in case of TEEs.

Booting up TDX takes more time than booting up a normal VM. Those
values are being already used as part of the CCv0 branch, and we're just
bringing them to the `main` branch as well.

The socket file for shim management is created in /run/kata
and it isn't deleted after the container is stopped. After
running and stopping thousands of containers /run folder
will run out of space.

1. when we use nerdctl to setup network for kata, no netns is created by
nerdctl, kata need to create netns by its own
2. after start VM, nerdctl will call cni plugin via oci hook, we need to
rescan the netns after the interfaces have been created, and hotplug
the network device into the VM

As the QEMU configuration for TDX differs quite a lot from the normal
QEMU configuration, let's add a new configuration file for the QEMU TDX.

Since TDX doesn't support readonly memslot, TDVF cannot be mapped as
pflash device and it actually works as RAM. "-bios" option is chosen to
load TDVF.
OVMF is the opensource firmware that implements the TDVF support. Thus
the command line to specify and load TDVF is ``-bios OVMF.fd``

Let's make sure we also check /sys/firmwares/tdx for TDX guest

or not.
