[FLINK-8176][flip6] Start SubmittedJobGraphStore in Dispatcher
## What is the purpose of the change
The FLIP-6 dispatcher never calls `start()` on its SubmittedJobGraphStore
instance. Hence, when a Job is submitted (YARN session mode with HA enabled),
an IllegalStateException is thrown. This pull request adds the necessary
changes so that jobs can be submitted.
## Brief change log
- *Implement SubmittedJobGraphListener interface in Dispatcher*
## Verifying this change
- *Added unit tests for new methods in Dispatcher class*
- *Verified that jobs can be submitted in FLIP-6 YARN session mode with
HA. Did not verify anything else.*
## Does this pull request potentially affect one of the following parts:
- Dependencies (does it add or upgrade a dependency): (yes / **no**)
- The public API, i.e., is any changed class annotated with
`@Public(Evolving)`: (yes / **no**)
- The serializers: (yes / **no** / don't know)
- The runtime per-record code paths (performance sensitive): (yes /
**no** / don't know)
- Anything that affects deployment or recovery: JobManager (and its
components), Checkpointing, Yarn/Mesos, ZooKeeper: (**yes** / no / don't know)
- The S3 file system connector: (yes / **no** / don't know)
## Documentation
- Does this pull request introduce a new feature? (yes / **no**)
- If yes, how is the feature documented? (**not applicable** / docs /
JavaDocs / not documented)

[FLINK-8176][flip6] Implement SubmittedJobGraphListener interface in
Dispatcher
Call start() on SubmittedJobGraphStore with Dispatcher as listener. To
enable
this, the dispatcher must implement the SubmittedJobGraphListener
interface. Add
simple unit tests for the new methods. Refactor DispatcherTest to remove
redundancy.
