> Currently MutatedConfigurationException is printed as:

> org.apache.flink.client.program.MutatedConfigurationException:
> Configuration execution.sorted-inputs.enabled:true not allowed.

> Configuration execution.checkpointing.mode:EXACTLY_ONCE not allowed in

> Which is slightly confusing. First not allowed configuration is listed in the
> same line as the exception name, which (especially if wrapped) can make it
> more difficult than necessary for user to understand that this is a list of
> violations. I'm proposing to change it to:
> {noformat}
> org.apache.flink.client.program.MutatedConfigurationException: Not
> allowed configuration change(s) were detected:
> - Configuration execution.sorted-inputs.enabled:true not allowed.
> - Configuration execution.runtime-mode was changed from STREAMING to
> BATCH.
> - Configuration execution.checkpointing.interval:500 ms not allowed in
> the configuration object CheckpointConfig.
> - Configuration execution.checkpointing.mode:EXACTLY_ONCE not allowed in
> the configuration object CheckpointConfig.
> - Configuration pipeline.max-parallelism:1024 not allowed in the
> configuration object ExecutionConfig.
> - Configuration parallelism.default:25 not allowed in the configuration
> object ExecutionConfig.
