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

Describe the solution you'd like:
If the Get returns a microvm with a status of failed then we should have an failure reason/message

Why do you want this feature:
This is so we can report the error in the capmvm machine controller.

Anything else you would like to add:
[Miscellaneous information that will assist in solving the issue.]

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

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
