Add 'chaos' test utility and 2 example tests

Browse Source 
'Chaos' is a new a group of test that validates behavior in presence of
random failures.

Overview:
 - Introduce a 'Chaos Monkey' controller which can unleash a monkey
against a test cluster.
 - Introduce a monkey of type 'ClusterBouncer' which stops and restarts
nodes according to some configuration
 - Add 2 example tests, they ensure a cluster can survive some amount of
nodes bouncing
 - Configure the build to skip chaos tests unless explicitly requested
 - Add some test utility functions
