> Abstract a LockManager to manage locks. 
> Some requirements for this LockManager:
>  * Cached a fixed number lock instances, such as: 1000
>  * Assign a Lock instance to a key and keep this mapping until the key released this instance
>  * This LockManager needs a high performance, such as: QPS 1000w
>  
> Some implementations that we can refer to:
>  * alluxio.collections.LockPool in Alluxio
>  * Implementation in MEITUAN !image-2024-08-14-17-17-28-792.png|width=205,height=196!
