What happens with the jars on HDFS if the last `BlobServer` dies without
properly calling `shutdown`? They will only be removed if a new Flink cluster
is started with the same `STATE_BACKEND_FS_RECOVERY_PATH` and shut down
properly?
> Make user jars available for all job managers to recover

> This is a bug in https://github.com/apache/flink/pull/1153.
> In case of multiple job managers, the user jars need to be accessible by all
> job managers (including those who arrive later).
> Since #1153 requires the file state backend to be configured, the simplest
> solution is to make the blob server aware of the configured recovery mode and
> put/get/delete the user jars from the file state backend as well.
