Install instructions

I see mentions that some small changes are required in Docker to use this library, from a Redhat blog post mentioning this project. There's no mentions of how to integrate these in a Docker host. Are there special steps? Running this example on Ubuntu results in an error:

FROM fedora:latest
ENV container docker
RUN yum -y update && yum -y install httpd && yum clean all
RUN systemctl mask dnf-makecache.timer && systemctl enable httpd
CMD [ "/sbin/init" ]

-> % docker run -ti --stop-signal=RTMIN+3 httpd
Failed to mount tmpfs at /run: Operation not permitted
[!!!!!!] Failed to mount API filesystems, freezing.
Freezing execution.

Based on this, it appears only projectatomic/docker can use these hooks. https://pagure.io/atomic-wg/issue/233

Correct Upstream Docker did not accept patches to automatically run oci hooks.

We should be able to get this to work with CRI-O and eventually Podman.
