Support the Docker daemon flag "insecure-registry=[]"

[mcoms]

I'd love to see support for this flag, which allows Docker to pull from named registries which use plain text authentication, or self-signed SSL certificates.

In v1.3.1, the format is: --insecure-registry self-signed-cert-registry.example.com:5000 when starting the Docker daemon.

It is possible to do this with the "options" daemon attribute under the node['docker'] namespace.

 "docker": {
   "options": "--insecure-registry self-signed-cert-registry.example.com:5000"
}

Yes, it is possible to do this with node['docker']['options'] but since that attribute is String so it won't play nice with attribute merging (eg. cannot inject the insecure registry via a role and leave the user free to supply its own custom options). I will work on a PR since I need the feature (and also support for the 'registry-mirror' option which works in a similar manner).

Thanks both — I use Docker with custom options for init/restarts, and hit that merge problem. For now I've specified the full line as options. Look forward to switching to insecure-registry when #232 is merged :)

I'm closing this issue since the PR has been merged and will be released in 0.37.
