Emit the NICo PowerShelf ID and serial through the shared OTLP resource projection so PowerShelf telemetry can be correlated without endpoint-based inference. Both log and metric exports inherit the attributes without collector-specific changes. Signed-off-by: Joseph Shifflett <jshifflett@nvidia.com>

WalkthroughPowerShelf serial metadata is now optional. Log identity uses serial, PowerShelf ID, or BMC MAC fallback. Shared OTLP resource conversion exports the PowerShelf ID and serial number when available, and omits unavailable serial data. ChangesPowerShelf identity metadata
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR adds PowerShelf identity attributes to OTLP resources without evidence of a correctness or runtime issue, but documentation for the changed public identity semantics remains incomplete and should receive explicit owner follow-up.

Model PowerShelf hardware serials as optional and stop substituting names, IDs, or MAC addresses before OTLP export. Retain stable log identity through PowerShelf ID and MAC fallbacks, and cover explicit and missing serial paths. Signed-off-by: Joseph Shifflett <jshifflett@nvidia.com>

NICo Hardware Health identifies PowerShelf telemetry with
component.type=power_shelf, but its shared OTLP resources do not include thePowerShelf ID or serial. Consumers therefore have to infer PowerShelf identity
from endpoint information.
This change adds
power_shelf.idwhen the managed PowerShelf ID is availableand
power_shelf.serial_numberfrom the existing PowerShelf metadata. BothOTLP logs and metrics use the shared resource-attribute projection, so existing
collectors receive the identity without collector-specific changes. Existing
resource attributes remain unchanged.
