I have Mesos 0.20.1 and Marathon 0.7.3
When marathon is creating a new App, and asks Mesos to start an instance, what
docker command is run by mesos?
The reason I ask is that I am referencing a docker container without a tag,
expecting the tag latest to be used. And that seems to work. But
I had a similar issue and what I ended up doing was to explicitly set the
version tag instead of just saying :latest. That makes the whole system much
more stable/predictable. For the cost of a single curl call when you push is
much better for debugging issues and the state of the system.

Originally we don't want to always pull with latest as that's what docker
run does as well which skips pull if the image exists, and has different
issues involved with this.
However with MESOS-1886 we can make this optional, just figuring out where
this configuration should be, at the latest
