> PHOENIX-29 added a new optimization in which we wont use HBase side
> ExplicitColumnTracker and seeks to columns (When query selects selective
> columns). This will be useful when there are less number of columns/versions
> whic are excluded. But when there are many column/versions which can be
> skipped (If the seeks can jump over some HFile blocks) the old way will be
> better.
> This issue adds two Hints in select for the user to explicitely tell whether
> to use the column seek model or non seek model
