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. Signed-off-by: Alex Ellis (OpenFaaS Ltd) <alexellis2@gmail.com>
