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.

In this commit, we have done:
* modify the tranfer process from grpc::Hooks to oci::Hooks, so the code
can be more clean
* add more tests for create_runtime, create_container, start_container hooks

StartContainer will be execute in guest container namespace in Kata.
The Hook Path of this kind of hook is also in guest container namespace.
StartContainer is executed after start operation is called, and it
should be executed before user-specific command is executed.

CreateContainer hook is one kind of OCI hook. In kata, it will be
executed after VM is started, before container is created, and after
CreateRuntime is executed.
The hook path of CreateContainer hook is in host runtime namespace, but
it will be executed in host vmm namespace.

According to the runtime OCI Spec, there can be some hook
operations in the lifecycle of the container. In these hook
operations, the runtime can execute some commands. There are different
points in time in the container lifecycle and different hook types
can be executed.
In this commit, we are now supporting 4 types of hooks(same in
runtime-go): Prestart hook, CreateRuntime hook, Poststart hook and
Poststop hook.

One of the checks done by cargo-deny is ensuring all crates have a valid
license. As the rust programs import each other, cargo.toml files
without licenses trigger the check. While I could disable this check
this would be bad practice.
This adds an Apache-2.0 license in the Cargo.toml files.
Some of these files already had a header comment saying it is an Apache
license. As the entire project itself is under an Apache-2.0 license, I
assumed all individual components would also be covered under that
license.

Update the agent protocol definition to introduce support for setting
and getting iptables from the guest.
Signed-off-by: Eric Ernst <eric_ernst@apple.com>
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.
