Docker: Live restore option for containers

Docker 1.12 has a nice set of improvements that significantly improve the ability to administrate the Docker daemon. https://t.co/bXt4PwPXRr

On the Docker GitHub release/changelog page of v1.12.0 under the Runtime section the first point:

Add --live-restore daemon flag to keep containers running when daemon shuts down, and regain control on startup #23213

This new option allows containers to keep running even when stopping, restarting or upgrading the Docker daemon.

TL;DR The --live-restore flag keeps containers running during a Docker daemon update.
