including qemu, firecracker, etc. for now, it has two scenarios,
one for NVDIMM, one for virtio-blk.

Firecracker does not support pci. It also uses kbd to implement reboot/reset.
Fix the kernel boot params to address this.
It also does not have good entropy at startup. Use the hardware random
number generator to support entropy.

Kata support specifing the default VM configuration via
configuration.toml. This allows the system or cluster admin
to choose the default (i.e minimum) size of the VM.
Add support in kata to respect the VM configuration for firecracker.
Also refactor some code to make error handling uniform.

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.

gometalinter is deprecated and will be archived April '19. The
suggestion is to switch to golangci-lint which is apparently 5x faster
than gometalinter.

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.

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.

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.

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.

The Network API no longer supports the state field. Using the
state field causes the API call to fail.
Note: The firecracker binary needs to be updated to match the API
as the older versions will expect the state field.

Because firecracker currently does not support a proper stop from
the caller, and because we don't want the agent to initiate a reboot
to shutdown the VM, the simplest and most efficient solution at the
moement is to signal the VM process with SIGTERM first, followed by
a SIGKILL if the process is still around.

Use the firecracker rescan logic to update the pre-attached drive.
This allows us to emulate hotplug.
Initially the drive backing stores are set to empty files on the
host. Once the actual block based device or file is available
swap the backing store.
The rescan needs to be issued iff the VM is running.

Unlike QEMU firecracker cannot accept a fd as part of the REST API.
Close the vsock vhostfd close to the point where we launch the VM.

Initial Support for the firecracker VMM
Note:
- 9p is unsupported by firecracker
- Enable pseudo hotplug block device hotplug capability
Initially, this will be a pseudo capability for Firecracker hypervisor,
but we will utilize a pool of block devices and block device rescan as a
temporary workaround.
