Description

In KIP-726, we want to make "cooperative-sticky, range" as default assignor. But before this can be applied, we need to handle some important cooperative-sticky assignor bugs first. We plan to implement it in early V3.1. In V3.0, we plan to make "range, cooperative-sticky" as the default assignor, so that if user wants to use cooperative-sticky assignor from old version byte-code, they just need 1 rolling bounce, to set the cooperative-sticky assignor in the PARTITION_ASSIGNMENT_STRATEGY_CONFIG config.
