Alex Ellis (OpenFaaS Ltd) 42e9c91ee9 Initial merge of faas-containerd
This patch completes part of the work in #20 by porting the code
for faas-containerd in-tree. When tested, I was able to deploy
and then remove figlet from the store on `x86_64`.

In a follow-up PR, duplication will be removed where possible
and consolidated with updated documentation.
