    Description

      To improve coverage of rollback/write conflict code throughout the server, add a failpoint to the WiredTiger storage engine that causes some percentage of write operations to throw WriteConflictException. Then, add a flag to smoke.py and change the test support libraries appropriately (ReplSetTest, ShardingTest, startMongoProgram) to set that failpoint in all mongods running under test.
