Some vmms, such as dragonball, will actively help us
perform online cpu operations when doing cpu hotplug.
Under the old onlineCpuMem interface, it is difficult
to adapt to this situation.
So we modify the semantics of nb_cpus in onlineCpuMemRequest.
In the original semantics, nb_cpus represents the number of
newly added CPUs that need to be online. The modified
semantics become that the number of online CPUs in the guest
needs to be guaranteed.

Update the agent protocol definition to introduce support for setting
and getting iptables from the guest.

This change adds two fields to the Storage pb
FSGroup which is a group id that the runtime
specifies to indicate to the agent to perform a
chown of the mounted volume to the specified
group id after mounting is complete in the guest.
FSGroupChangePolicy which is a policy to indicate
whether to always perform the group id ownership
change or only if the root directory group id
does not match with the desired group id.
These two fields will allow CSI plugins to indicate
to Kata that after the block device is mounted in
the guest, group id ownership change should be performed
on that volume.
