## What changes were proposed in this pull request? Currently when an apply transaction fails on ContainerStateMachine, the [isStateMachineHealthy](https://github.com/apache/ozone/blob/bf19af946aa08d2bea5064d79513a196b9bbf646/hadoop-hdds/container-service/src/main/java/org/apache/hadoop/ozone/container/common/transport/server/ratis/ContainerStateMachine.java#L568) flag is set to false. However when the next set of transactions are applied this flag is not checked and all the transactions in the pipeline can get applied to the statemachine which could potentially bring down the statemachine in an inconsistent state. For instance if the write chunk fails and the next putBlock transaction succeeds then this would mean that the container is in an inconsistent state. In this patch an unhealthyContainerSet is added to ensure no future transactions gets applied to the container if the container is present in the unhealthyContainerSet. A container would be added to containerSet if any errors are seen while writing StateMachine data/reading StateMachineData/applyTransactions to the container. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-12236 ## How was this patch tested?
