> Now we always use the default timeout configured for zk and meta.
> I think it is reasonable to always use the same timeout when accessing zk and meta as
the result will be shared by lots of threads. If we could do a successful fetching then the
result will be in cache so it does not make sense to set the timeout to a very small value
when fetching.
> But I think it is also important to let the user request finish in time even if the user
can only get a timeout exception. We should not block a user request longer than operation
timeout.
> So I think we could add a timeout parameter to the region locate method, and if the location
can not be fetched in time, we will just finished the returned CompletableFuture with a timeout
exception, but the actual fetching operation can still go on and use its own timeout config.
