Our optimizer tests have become flaky due to often timing out:
* https://www.internalfb.com/intern/test/281475048520501?ref_report_id=0
* https://www.internalfb.com/intern/test/281475048520502?ref_report_id=0

{F778290241}{F778290240}

This diff splits tests that run multiple optimizer through training.
Also reduced number of iterations and number of datapoints for evaluation. At the moment we aren't really verifying end result value, so I assume this reduction shouldn't matter.
