Run acceptance tests with different configs using @Parameterized

This is a simpler approach as it doesn't require generating extra test
targets for Buck, nor rebuilding test jars to get everything working
in Eclipse. There are enough tests running at any given time with Buck
that having each acceptance test take twice as long should maintain
adequate parallelism.
