In the context of CRI, in order to make cAdvisor work in a standalone way without resorting to api-service, we need to expose more information related to pods and apps directly in the JSON output of rkt list and rkt status.

Looking at current cadvisor implementation, it looks like we are currently missing at least the following fields:

• pod IPs (on non-running pods)
• pod cgroups
• per-app rootfs directory
