Hi Zvika,

To share a sessiond the LTTng home and run directories, and the shared 
memory should be shared between the containers.

Eg. https://github.com/mjeanson/gcloud-lttng/blob/master/pods/demo1.yaml.in

In a scenario with multiple sessionds (eg. one per container), the 
traces could be combined in post using babeltrace.
