DRILL-3927: use OutOfMemoryException in more places
Some code cleanup required for the upcoming introduction of the rewritten
direct memory allocator. Chiefly the introduction of OutOfMemoryException
handling in a few spots, the use of DrillAutoCloseables for some allocator
close() calls, and some other minor cleanup.
- removed the exclusion of exec/work from the jdbc-all jar, because it now
depends on OutOfMemoryException, and that is derived from
FragmentSetupException and Foreman Exception
this closes #199
