Description

BigtableIO.Read takes a table and a filter, but does not let the user customize the row range. If a user wants to scan a relatively narrow range, they can do it by specifying a filter ("starts with abcd") or ("less than abcd"), but under the hood Cloud Bigtable will implement this as a full table scan -> filter instead of a narrower scan.

We should expose these setters publicly so that users can implement row scans directly.
