[FLINK-8785][rest] Handle JobSubmissionExceptions
## What is the purpose of the change
Currently, if a `JobSubmissionException` occurs the `JobSubmissionHandler`
only returns `505 Internal server error.`, with no details about the original
exception.
This PR modifies the handler to returns the messages of all exceptions in
the stack trace.
## Brief change log
* modify `RestHandlerException` to allow multiple error messages, similar
to `ErrorResponseBody`
* modify `JobSubmitHandler` to handle exceptions during the job submission
## Verifying this change
* see `JobSubmitHandlerTest#testFailedJobSubmission
