> 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.
