78ea50c36c virtcontainers: Jailer: Add jailer support for firecracker
Firecracker provides a jailer to constrain the VMM. Use this
jailer to launch the firecracker VMM instead of launching it
directly from the kata-runtime.

The jailer will ensure that the firecracker VMM will run
in its own network and mount namespace. All assets required
by the VMM have to be present within these namespaces.
The assets need to be copied or bind mounted into the chroot
location setup by jailer in order for firecracker to access
these resouces. This includes files, device nodes and all
other assets.

Jailer automatically sets up the jail to have access to
kvm and vhost-vsock.

If a jailer is not available (i.e. not setup in the toml)
for a given hypervisor the runtime will act as the jailer.

Also enhance the hypervisor interface and unit tests to
include the network namespace. This allows the hypervisor
to choose how and where to lauch the VMM process, vs
virtcontainers directly launching the VMM process.

16fe8553af qemu: Remove the storage directories if qemu get from the factory
Store related in directory /var/lib/vc/sbs and /run/vc/sbs if
vm template is enabled.
The cause is NewVM and NewVMFromGrpc will create vcStore with
VM's ID and set it as store of hypervisor if the factory is enabled.

This commit record the VM's ID to HypervisorConfig.VMid and remove
directories in qemu.cleanupVM to handle the issue.

ace81155a4 factory: Make factory status can show status of VMCache server
This commit adds a new gRPC function Status to CacheService.  VMCache
server will reply the status of VMCache server.
Factory destroy will call gRPC Status to get the status of VMCache
server and output it when VMCache is enabled.

47670fcf73 memoryDevice: reconstruct memoryDevice
If kata-runtime supports memory hotplug via probe interface, we need to reconstruct
memoryDevice to store relevant status, which are addr and probe. addr specifies the
physical address of the memory device, and probe determines it is hotplugged via
acpi-driven or probe interface.

90704c8bb6 VMCache: the core and the client
VMCache is a new function that creates VMs as caches before using it.
It helps speed up new container creation.
The function consists of a server and some clients communicating
through Unix socket.  The protocol is gRPC in protocols/cache/cache.proto.
The VMCache server will create some VMs and cache them by factory cache.
It will convert the VM to gRPC format and transport it when gets
requestion from clients.
Factory grpccache is the VMCache client.  It will request gRPC format
VM and convert it back to a VM.  If VMCache function is enabled,
kata-runtime will request VM from factory grpccache when it creates
a new sandbox.

VMCache has two options.
vm_cache_number specifies the number of caches of VMCache:
unspecified or == 0   --> VMCache is disabled
> 0                   --> will be set to the specified number
vm_cache_endpoint specifies the address of the Unix socket.

This commit just includes the core and the client of VMCache.

Currently, VM cache still cannot work with VM templating and vsock.
And just support qemu.

fad23ea54e virtcontainers: Conversion to Stores
We convert the whole virtcontainers code to use the store package
instead of the resource_storage one. The resource_storage removal will
happen in a separate change for a more logical split.

This change is fairly big but mostly does not change the code logic.
What really changes is when we create a store for a container or a
sandbox. We now need to explictly do so instead of just assigning a
filesystem{} instance. Other than that, the logic is kept intact.

cf22f402d8 virtcontainers: Remove the hypervisor waitSandbox method
We always call waitSandbox after we start the VM (startSandbox), so
let's simplify the hypervisor interface and integrate waiting for the VM
into startSandbox.
This makes startSandbox a blocking call, but that is practically the
case today.

763bf18daa virtcontainers: Remove the hypervisor init method
We always combine the hypervisor init and createSandbox, because what
we're trying to do is simply that: Set the hypervisor and have it create
a sandbox.

Instead of keeping a method with vague semantics, remove init and
integrate the actual hypervisor setup phase into the createSandbox one.

20f2d30ab8 virtcontainers: share the agent's client between factory's VM and sandbox
When agent is configured as longLive, the VM's agent created
by factory will not close it's client once it connected, thus
the sandbox's agent cannot re-connect successfully.

Sharing the agent's client between VM's agent and sandbox
can fix this issue.

c518b1ef00 device: use devicemanager to manage rootfs block
Fixes #635

When container rootfs is block based in devicemapper use case, we can re-use
sandbox device manager to manage rootfs block plug/unplug, we don't detailed
description of block in container state file, instead we only need a Block index
referencing sandbox device.

Remove `HotpluggedDrive` and `RootfsPCIAddr` from state file because it's not
necessary any more.
