> The current logic of ReadIndex limits the performance of FollowerRead.
>  
> In production, the vast majority of requests are for old data, so running the readIndex logic for every request becomes somewhat wasteful.
> This ticket is to introduce LocalLease for followers, so that followers can decide if it's catched up with Leader, and application can reasonably make use of this information.
