Telemetry Instrumentation

How to instrument code in vscode-documentdb to produce actionable telemetry.

The @microsoft/vscode-azext-utils library automatically captures these — never add them manually:

Auto-captured	Details
Duration	`measurements.duration` — wall-clock ms from callback start to end
Result	`properties.result` — `"Succeeded"`, `"Failed"`, or `"Canceled"`
Error info	`properties.error` (name), `properties.errorMessage` (message)
Cancel detection	`UserCancelledError` sets result to `"Canceled"` automatically
Machine/session IDs	`VSCodeMachineId`, `VSCodeSessionId` — always present
Extension metadata	Extension name, version, VS Code version

Do not re-measure duration, set result, or catch errors just for telemetry — the wrapper handles it.
