DPAL-1039 Support non-MR fetching for simple queries with select/limit/filter
operations only
It's trivial but frequently asked by end-users. Currently, select queries
with simple conditions or limit should run MR job which takes some time
especially for big tables, making the people irritated.
For that kind of simple queries, using fetch task would make them happy.
