Automatic Benchmark Command Submission for New Devices in Datasets

Today, when new devices are added through an ADT rebuild and new Network Intents are created, the commands required to benchmark those devices for Datasets must be submitted manually for each new device, creating ongoing administrative overhead as the network evolves. This enhancement would automatically submit the relevant benchmark commands for newly discovered devices, while still allowing an administrator to manually approve the submitted commands before they take effect. An alert or email notification when new commands are awaiting approval would keep administrators informed without requiring constant manual monitoring. This would make Datasets easier to maintain in environments where the network topology and device inventory change frequently.
