With the support of NVMe Discard operations introduced by oxidecomputer/propolis#1105, we should add Oximeter stats related to these operations, to match https://github.com/oxidecomputer/omicron/blob/main/oximeter/oximeter/schema/virtual-disk.toml:
- discards
- failed-discards
- add this to io-latency and io-size and make sure this is a new io-kind of operation
