Today for virtiofsd kata sets by default `cache=always`. This option is
useful for performance but if the shared files are modified from the
host changes are not updated in the guest as virtiofsd uses cached value
all time.
This patch changes to `cache=auto` to fix consistency issues. The option
can still be set to always if it is wanted by the user.

The user sometimes doesn't care about pmu usage(e.g. perf tool profiling).
But pmu will cost significant overhead on boot time and virtualization
context switch. E.g. on arm64, if guest pmu is enabled, kvm should save
and restore all PMU registers when guest/host switching.

To control whether guest can enable/disable some CPU features. E.g. pmu=off,
vmx=off. As discussed in the thread [1], the best approach is to let users
specify them. How about adding a new option in the configuration file.
Currently this patch only supports this option in qemu,no other vmm.

Some network plugins add static arp entries in the network namespace.
Scan namespace for static entries and pass these on to the
agent to be added within the guest.
If the grpc api is not implemented by the agent due to a older running
agent, check for this and do not error out to maintain
backward compatibility.

Use systemd-cat to collect hypervisor output. The `systemd-cat` program
will open a journal fd and call `cat(1)` to redirect all the output to
the fd. This requires an extra binary to read from hypervisor stdout
(that has combined stdin, stderr and serial terminal). But because it is
cat the overhead is minimal and only is started on Kata debug mode.

After removing dectect of host gic version, we need to limit the max vCPU
in different cases.
Given that in most cases, Kata is running on gicv3 host, set it as default
value. If the user really want to run Kata on gicv2 host, he/she need to
set default_maxvcpus in toml file to 8 instead of 0.
In summary, If the user uses host gicv3 gicv4, everything is fine
If the user uses host gicv2, set default_maxvcpus=8

Commit b4385901da ("qemu/arm64: Detect host GIC version to configure guest
GIC") reads /proc/interrupts to detect the host gic version.
But on a ThunderX2 host with 224 cpus, the /proc/interrupts is ~762K bytes.
Hence it will costs ~900K bytes memory overhead.
From the go tool pprof results:
flat flat% sum% cum cum%
976.89kB 100% 100% 976.89kB 100% github.com/kata-containers/runtime/virtcontainers.getHostGICVersion
Although the allocated memory will be freed, seems it worthy removing that
for speed up the runtime.
As per [1], there is no perfect way to detect the gic version on host.
At qemu side, if we use "gic-version=host", qemu will automatically detect
the verion by kvm ioctl. So we'd better let qemu determine the gic version.
If the user really want to start vm with gic-verion=2, he/she can set it
in machine_accelerators option.
