> As part of *HDDS-8974. Introduce detailed lock information*
> Below omLockDetails is declared which is private to the instance and consume thread local resource of thread. But this resource is never released.
> private final ThreadLocal<OMLockDetails> omLockDetails =
> ThreadLocal.withInitial(OMLockDetails::new);
>  
> This will cause memory leak and thread local memory keeps increasing with each new Request object.
>  
> Need avoid usages of thread local as instance level; or need use as static or as singleton to reuse same resource.
