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.

In order to move the hypervisor implementations into their own package,
we need to put the capabilities type into the types package.

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.

This includes cleaning up the sandbox on disk resources,
and closing open fds when preparing the hypervisor.

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.
Note: This is still racy.

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.
