Project: Hadoop Distributed Data Store
Issue Type: Sub-task

RATIS-573 would add notification to the State Machine on encountering failure
during Log append.
The scope of this jira is to build on RATIS-573 and define the handling for log
append failure in Container State Machine.
1. Enqueue pipeline unhealthy action to SCM, add a reason code to the message.
2. Trigger heartbeat to SCM
3. Notify Ratis volume unhealthy to the Datanode, so that DN can trigger async
volume checker
Changes in the SCM to leverage the additional failure reason code, is outside
the scope of this jira.
