When there are many inactive partitions in the cluster, we observed constant churn of URP in the cluster even if follower can catch up with leader's byte-in-rate because leader broker frequently moves replicas of inactive partitions out of ISR. This PR mitigates this issue by not moving replica out of ISR if follower's LEO == leader's LEO.
