[FLINK-8943] [ha] Fail Dispatcher if jobs cannot be recovered from HA store
## What is the purpose of the change
In HA mode, the Dispatcher should fail if it cannot recover the persisted
jobs. The idea
is that another Dispatcher will be brought up and tries it again. This is
better than
simply dropping the not recovered jobs.
