Add NVIDIA docker configurations

[arnaldo2792]

Issue number:
Closes #2087

Description of changes:

This adds the shimpei and docker configurations to set up the `nvidia`
runtime for variants that use docker as their containers runtime.

Testing done:

• In aws-k8s-1.21-nvidia, I confirmed that the shimpei configurations were created for the nvidia runtime
• In a local build of a new ECS variant that uses the new nvidia-oci-hooks-docker.toml and docker-daemon-nvidia.toml, I confirmed that shimpei configurations were created for both the default and nvidia runtimes, and that the docker configuration included both runtimes as in daemon-nvidia-json:

# Shimpei configurations
bash-5.1# ls /etc/shimpei/
nvidia-oci-hooks.json  shimpei-hooks.json

# Docker configuration with both runtimes
[root@admin]# cat /.bottlerocket/rootfs/etc/docker/daemon.json
{
  "log-driver": "journald",
  "live-restore": true,
  "max-concurrent-downloads": 10,
  "storage-driver": "overlay2",
  "exec-opts": ["native.cgroupdriver=cgroupfs"],
  "data-root": "/var/lib/docker",
  "default-runtime": "nvidia",
  "runtimes": { "shimpei": { "path": "shimpei" }, "nvidia": { "path": "nvidia-oci" } },
  "selinux-enabled": true,
  "default-ulimits": { "nofile": { "Name": "nofile", "Soft": 1024, "Hard": 4096 } }
}

Reviewers can see the local variant in this branch, I used that branch to test an ECS task that uses GPUs.
