Pre/Post backup routine scripts about docker-volume-backup HOT 3 CLOSED

This is a good idea, but also pretty tricky to implement.

Mounting a script into the backup container and running it on certain occasions would be very simple, but won't be of much help as you likely want to run these scripts inside the application containers. This could be done using labels containing a command on the application containers, but that creates a few other obstacles:

• replicating the behavior of docker exec using the Docker client is ridiculously hard, I failed to get it working once (it should be possible though)
• this setup also gets tricky once you have multiple backup containers running in a setup: which backup container is supposed to trigger which commands? This probably could work like the stop-label mechanism, but I haven't thought it through entirely.

Considering this feature would take quite some time to implement and I don't need it myself I probably won't implement it too soon (there are other missing features like #29 that I would be using myself). If anyone wants to work on this though I am happy to give advice and merge PRs.
