metrics: make pods_per_gb valid JSON

Under some circumstances, the pod_per_gb value would come out as <0, and be generated without any leading 0's (such as `.14` rather than `0.14`). This is not valid JSON, and would break the report generation parsing in R. Use `printf` to force a leading 0 prefix onto the value. Signed-off-by: Graham Whaley <[email protected]>
