From bd2940861c282dfc39309bca94378c820ab7df7e Mon Sep 17 00:00:00 2001

Subject: End to end tests refs #3 (#10)

* Separate docs for containerd 1.1 and 1.2

The configuration for the untrusted workload annotation and runtime
class are different enough that it makes sense to separate the docs.

Commands in docs are taken from scripts in the docs/scripts directory.
These scripts can be used later for integration & doc tests (#3). The
docs can be updated using the embedmd tool:
https://github.com/campoy/embedmd

* Add basic e2e tests refs #3

Added end-to-end tests based on the quickstart workflows for
containerd 1.1 and containerd 1.2+.
