The --skip-preflight-checks flag has been deprecated in the Kubernetes v1.9
and removed from Kubernetes v1.12.
We should use --ignore-preflight-errors=all flag instead of --skip-preflight-checks.

Update the developer guide to add instructions of how to get the
correct version of the QEMU source and sets your_qemu_directory

community to understand

When starting a container and dropping all capabilities,
the init child process has no permission to read the exec.fifo
file because the parent set the file mode 0o622. So change the exec.fifo file mode to 0o644.

Without this, if the shim dies, we will not have a reliable way to
identify what mounts should be cleaned up if `containerd-shim-kata-v2
cleanup` is called for the sandbox.
Before this, if you `ctr run` with a sandbox bindmount defined and SIGKILL the
containerd-shim-kata-v2, you'll notice the sandbox bindmount left on
host.
With this change, the shim is able to get the sandbox bindmount
information from disk and do the appropriate cleanup.

If for any reason there's an error when trying to setup the sandbox
bindmounts, make sure we roll back any mounts already created when
setting up the sandbox.
Without this, we'd leave shared directory mount and potentially
sandbox-bindmounts on the host.

While evaluating the possibility of having kata-agent statically linked
to the GNU libc, we've ended up facing some issues with prctl.
When debugging the issues, we figured out that the crate hasn't been
maintained since 2015 and that the capctl one is a good 1:1 replacement
for what we need.

When hotplug memory on arm64 in kata, kernel will shout:
[ 0.396551] Block size [0x40000000] unaligned hotplug range: start 0xc8000000, size 0x40000000
[ 0.396556] acpi PNP0C80:01: add_memory failed
[ 0.396834] acpi PNP0C80:01: acpi_memory_enable_device() error
[ 0.396948] acpi PNP0C80:01: Enumeration failure
It means that kernel will check if the memory range to be hotplugged
align with 1G before plug the memory. So we should twist the qemu to
make sure the memory range align with 1G to pass the kernel check.

Here we offer a document to instruct user to enable it.

Since the propagation flags couldn't be combinted with the
standard mount flags, and they should be used with the remount,
thus it's better to split them from the standard mount flags.
