In case where we have same number of consumer and producer tablets, map tablets with the same key range so that the apply step on the consumer is a local call.

[#2679] Do smart consumer producer tablet mapping
5303af5 
Summary:
In cases where we have an equal num of consumer and producer tablets, do a smart mapping such that consumers poll from producers that have the same key range. This will result in a local operation on consumer apply.

To disable this change/force a remote lookup, set `cdc_force_remote_tserver=true`.
