Description

Currently column pagination filter takes (offset, limit) as the parameters. It then scans through until offset and then retrieves "limit" number of columns.

A lot of times we can do pagination in the following manner:
1) Provide offset=0, limit=50
2) Get <last_column_id> obtained and then Provide offset=<last_column_id>, limit=50 to get the next set of columns.

Since we can seek to column qualifier names - this will allow for faster pagination using columns and ColumnPaginationFilter (particularly if there are millions of columns).
