metrics: make pods_per_gb valid JSON

Browse Source 
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.
