Description

In Hadoop fair call queue feature, we can use RPC call's processing details to provide cost-based scheduler, this information needs the locks' wait, read and write time.

In Hadoop, these information can be easily get and set via threadLocal variables, but in Ratis enabled cluster, we can't do that as Hadoop. So this ticket is to change the lock interface to return a new Class as OMLockDetails to store this information.
