migrate/cpu-throttle: Add max-cpu-throttle migration parameter
Currently, the default maximum CPU throttle for migration is 99(CPU_THROTTLE_PCT_MAX). This is too big and can make a remarkable performance effect for the guest. We see a lot of packets latency exceed 500ms when the CPU_THROTTLE_PCT_MAX reached. This patch set adds a new max-cpu-throttle parameter to limit the CPU throttle.
