firecracker

weaveworks/footloose#259

Currently, ctriface/ doesn't pick up environment variables from the knative manifests. Firecracker-containerd supports it at a the container creation time as a runtime argument to the corresponding API call.

Example:

	container, err := o.client.NewContainer(
		ctx,
		vmID,
		containerd.WithSnapshotter(o.snapshotter),
		containerd.WithNewSnapshot(vmID, *vm.Image),
		containerd.With

What would be really helpful is if there were examples of using this driver.

Examples I would find particularly useful:

1. Connecting to another task within a group where one of those tasks is a Firecracker VM (does one just talk to localhost?)
2. Placing artifact data into the task
3. Working with environment variables, or noting that it's not possible to do so

Add a how to use section on readme
Add a guide on how to create a boot drive
Add a guide to compile the linux kernel for firecracker

What happened:
I created a mvm in namespace foo.
I ran ListMicroVMs pointing to namespace bar.

All mvms were returned (ie those in foo)

What did you expect to happen:
In this example, nothing should have been returned on the list call as I did not create anything in the bar namespace.

How to reproduce it:
Follow steps above.

https://github.com/qarax/qarax/blob/2162b4fdbc8dcf0bc383b8e09d18d49dd35540cf/qarax.yml currently only has the Host related operations and schemas.

Storage, Vm, Drive, Kernel should be added
