Investigate possible metrics to collect from the system

[jiayihu]

• System throughput (IoT + cluster)
• WASM Update time
• Service provision time
• WASM ML start-up time, memory usage, inference time vs normal ML image
• Inference time local vs cloud
• Probability of packet drop when sending CoAP or receiving the ack
• Other CoAP metrics like latency or bandwidth. I don't think I can get power consumption
• WASM performance on embedded (stack, heap usage, exec timing)
• Synthetic benchmark for the WASM module run in the embedded device
• WASM module dimension for pro-processing and ML model. OCI image dimension.
• Krustlet parallel WASM modules vs k3s
