Compose CLI - Rolling service restart

[will-chan]

Add an optional rancher-compose restart --batch-size "2" where it can restart "2" containers from a given service at a time rather than restarting all containers and potentially disrupting the service itself.

Also this could be useful(?) for rolling service restart

# Set the interval to 30 seconds, which is the time between 
# when the containers restart
$ rancher-compose restart service --interval "30000"

Tested with rancher-compose-v0.7.0-rc1
Rancher server - Build from master

Rolling restart is now supported from rancher-compose using the following command:

./rancher-compose -p test1 -f dc.yml restart --batch-size 2 --interval 30000

This should be available in the next rancher-server release.
