Sometimes, tested Kubernetes doesn't have direct access to Internet but
access through repository mirrors.
This patch handles this case for rally test case.
There's two ways for providing the repository mirrors:
- Give an environment variable (`MIRROR_REPO`) which gives a repository
mirro with all needed images.
- Gives an environment variable per needed repo:
- `DOCKERHUB_REPO` for DockerHub repository (`docker.io`)
- `GCR_REPO` for Google Cloud repository (`gcr.io`)
- `K8S_GCR_REPO` for Kubernetes repository (`k8s.gcr.io`)
Needed images list has also been extracted so Kubernetes administrator can
easily upload these images to the mirror if the mirror also doesn't have
access to Internet.
