add "chaos" acceptance test
add "chaos" acceptance test

this test is similar to the put test, but focuses on disrupting the
servers. in each iteration, a random subset of the nodes is killed
and restarted. the next iteration waits for any of the writers to
make progress (i.e., partial cluster recovery). a cyclic check
quickly aborts the test should nodes die unexpectedly inbetween
iterations.
