Issue 166

Rolling config change was very broken. ConfigCollectionBase was not processing rolling config correctly in
getConfigForThisInstance(). Also, when a rolling config change is started, the instance must wait until it
restarts at least once before advancing. Lastly, a test case to validate this was written.
Merge branch 'master' of git://github.com/Netflix/exhibitor into issue-166
Fixed asserts
fixing/updated existing tests for this change
rollingConfigChangeRestartCount was being set in the wrong place. Setting the initial value of restartCount in MonitorRunningInstance to non-zero exposed this.
Add test that does multiple rolling releases
