[FLINK-7041] Deserialize StateBackend from JobCheckpointingSettings with
user classloader
R: @tzulitai
CC: @StephanEwen I noticed that the state backend that is in the
configuration is never used anywhere. I'm guessing this is for future work or
is something missing in the code?

[FLINK-7041] Deserialize StateBackend from JobCheckpointingSettings with
user classloader
This also adds a test for serializability with a class that's not in the
default classloader.

> Key: FLINK-7041
> URL: https://issues.apache.org/jira/browse/FLINK-7041
> Project: Flink
> Issue Type: Bug
> Components: DataStream API, Distributed Coordination, State
> Backends, Checkpointing
> Affects Versions: 1.3.0, 1.3.1
> Reporter: Aljoscha Krettek
> Assignee: Aljoscha Krettek
> Priority: Blocker
> Fix For: 1.3.2
>
>
> A user ran into the problem that the {{SubmitJob}} message is not
> (de)serialisable if it contains custom RocksDB options (or a custom state
> backend): [1]
> The problem is that {{SubmitJob}} contains a {{JobGraph}} which contains
> {{JobCheckpointingSettings}} which contains a {{StateBackend}}. This
> {{StateBackend}} potentially has user code and therefore can only be
> deserialised with the user classloader.
> This issue is mostly identical to FLINK-6531.
