> Mesos Containerizer uses the command executor to actually launch the user defined command,
and the command executor then can communicate with the slave about the process lifecycle.
> When we provision a new container with the user specified image, we also need to be able
to run the command executor in the container to support the same semantics.
> One approach is to dynamically mount in a static binary of the command executor with
all its dependencies in a special directory so it doesn't interfere with the provisioned root
filesystem and configure the mesos containerizer to run the command executor in that directory.
