> applyTransaction is invoked from the Ratis pipeline and the ContainerStateMachine
> uses a async executor to complete the task.
>  
> We require a latency metric to track the performance of log apply operations in the state
machine. This will measure the end-to-end latency of apply which includes the queueing delay
in the executor queues. Combined with the latency measurement in HddsDispatcher, this will
be an indicator if the executors are overloaded.
