When a Nutanix Prism async data-protection domain returned by the Prism API did not contain a "usage_stats" entry (observed on freshly created protection domains that had not produced any snapshots yet), the "NTNX Data Protection" service went UNKNOWN with "KeyError: 'usage_stats'".

The check now tolerates missing usage statistics and reports an exclusive snapshot usage of 0 bytes for those protection domains. Replication bandwidth metrics are also only emitted when the corresponding values are present in the section.
