conjure-up Canonical Kubernetes in LXD

[Mark Shuttleworth]

Developers will love this, the ability to spin up k8s in multi-node mode
on a laptop is fantastic!

I wonder if it's worth providing a page of instructions for the sysctl
changes built-in to conjure-up?

We should aim to have the thing we socialize be one command ("conjure-up
canonical-kubernetes") and not a URL to a page with instructions.
Ideally, conjure-up would be able to detect the status of the machine,
tell the user how to adjust, and block until these changes have been
actioned (or do them for the user with approval).

Thoughts?
