[FLINK-3800] [runtime] Introduce SUSPENDED job status
The SUSPENDED job status is a new ExecutionGraph state which can be reached
from all
non-terminal states when calling suspend on the ExecutionGraph. Unlike the
FAILED,
FINISHED and CANCELED state, the SUSPENDED state does not trigger the
deletion of the
job from the HA storage. Therefore, this state can be used to handle the
loss of
leadership or the shutdown of a JobManager so that the ExecutionGraph is
stopped but
can still be recovered. SUSPENDED is also a terminal state but it can be
differentiated as
a locally terminal state from FAILED, CANCELED and FINISHED which are
globally
terminal states.
Add test case for suspend signal
Add test case for suspending restarting job
Add test case for HA job recovery when losing leadership
Add online documentation for the job status
