Review comment:
I just had an offline chat with @shahrs87 and I am +1 with keeping
scanner timeout as config for Lock, the intention is to:
1. not introduce more timeout configs and worsen timeout burden.
2. use the one which can help with multiple retries (if allowed within SLA)
rather than timeout which is available at entire operation level (rpc call +
lock + locate region by scan + retry if required + and so on...).
