- Assert that we don't create a container metric batch when the envelopes contain no container metrics - Change example units for cpu and log rate Co-authored-by: Matthew Kocher <matthew.kocher@broadcom.com>
- There is existing logic to set all container metrics to zero when any given reported container metric is missing. - Chose not to implement the same behaviour for cpu_entitlement as this would prevent other stats from being available before Diego Cells are upgraded.

Extend the existing v3 processes stats endpoint to include the CPU Entitlement for the process.
It can be difficult to reason about process CPU usage using the existing cpu stat. For example the value is impacted by changes to the underlying vCPUs available on the Diego Cell. CPU Entitlement is a more generally useful metric.
