Description

The observer should fetch the list checkpoints from the observed job and store the last savepoint into the status directly.

This is especially useful for terminal job states in Flink 1.15 as it allows us to avoid cornercases such as the operator failing after calling cancel-with-savepoint but before updating the status.
