[FLINK-9211][REST] JarRunHandler submits job to Dispatcher via RPC
## What is the purpose of the change
This PR reworks the `JarRunHandler` to submit the job to the dispatcher via
RPC, instead of setting up a `RestClusterClient` and going through the client's
job-submission routine.
The reasoning is that the existing behavior was causing issues on
kubernetes, and this change also removes a special-case as this was the only
handler that actively sends out rest requests.
## Brief change log
* `JarRunHandler` now has access to `DispatcherGateway`
* `JarRunHandler` now uploads jar and submits job via RPC
## Verifying this change
* run `JarRunHandlerTest`
* submit job through webUI
