Summary: Persist cause of task state transitions in
machine-readable format
Key: AURORA-778
URL: https://issues.apache.org/jira/browse/AURORA-778
Project: Aurora
Issue Type: Story

Add a new field to TaskEvents that identifies the cause of a transition and
export metrics based on the cause (in addition to state). This will be useful
to track down the cause of LOST tasks.
Possible implementation:
{noformat}
enum TransitionCause {
UNKNOWN = 0,
SLAVE_REMOVED = 1,
EXECUTOR_CRASHED = 2,
TIMED_OUT_BY_SCHEDULER = 3,
FORCE_TASK_STATE_RPC = 4,
// ...
}
{noformat}
