Review request for Sqoop.
Changes
-------

I've rebased my patch on current head of Sqoop2 branch.
Description
-------

I've implemented end-to-end behaviour to cover setting number of extractors and loaders. Current default is to have 10 extractors (=mappers) and equal number of loaders as extractors (= no reduce phase). Setting any number of loaders will add reduce phase.
This addresses bug SQOOP-737.
