limit the number of vertical scaling up that could have happened for a certain period of time

[sanposhiho]

Scaling down is limited so that it happens once an hour at max. But, when tortoise suggests scaling up, we always immediately try to scale up Pods for safety for now. It could cause many restarting happen in a very short period of time.

We know limitting scaling up could be dangerous, but we may want to limit it, to some extent, like scaling down.
