Agent should log other container statuses

If we give the agent access via rbac to its own pod, it can use the Kubernetes API to query the status of other containers in its pod. This would let us log container configuration errors, like missing secrets/configmaps, or image pull errors.

This might mean the agent takes a dependency on client-go.

Start by reviewing the Kubernetes API and RBAC needed for an agent to query other containers in its pod, then evaluate whether client-go is appropriate. Done means the agent logs container configuration errors, including missing secrets or configmaps, and image pull errors.
