Since docker update for changing quotas of containers is merged for 1.10 in #15078 (thanks @hqhq!) it's time to extend it to other useful parameters.

One of the options that I'm missing is the ability to change a container restart policy, which I mentioned in #15078, it also may cover request in #13743 issue.

Something like docker update --restart=always to change RestartPolicy to always would be great.
