While testing the consistency under pressure load, make sure cluster is making progress expecting all stressing client operations to complete without errors. No-op failure case could be added to etcd-tester.

Similar to --stresser=nop, --failures=nop can be added.

After running for a predetermined period of time, we stop injecting failures and give the system time to fully recover. Then we switch the test to liveness mode. The purpose for the liveness test is to verify that the system does not deadlock after a sequence of failures.
