Credentials Store

Now credentials store is supported in both credsStore and credHelpers manners.

Caveats

Digest will be lost, as when you save/load images.

Usage

pulldockerimage host/repository:tag > archive.tar
eg: index.docker.io/library/ubuntu:devel > ubuntu.tar

generate a docker image directly (without deploying to the client machine).

`docker login` is required prior if authorization is required.
If credsStore is not used, .docker/config.json should look like this.

{
        "auths": {
                "auth.docker.io": {
                        "auth": base64(username:password)
                }
        }
}
