> Convert unspecified edge to rescale when using adapive batch scheduler

> Key: FLINK-25046
> URL: https://issues.apache.org/jira/browse/FLINK-25046
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Coordination
> Reporter: Lijie Wang
> Assignee: Lijie Wang
> Priority: Major
> Labels: pull-request-available
>
> Currently, unspecified edges(partitioner == null) will be setted to
> {{FORWARD}} when the parallelism of both upstream and downstream is -1. This
> may cause many job vertices whose parallelism is not calculated based on data
> volume, but is aligned with their upstream vertices' parallelism because of
> forward edges, which is contrary to the original intention of our adaptive
> batch scheduler.
> For this problem, we will convert the unspecfied edges between OperatorChains
> to {{RESCALE}} edges(instead of {{FORWARD}} edges) after OperatorChains'
> creation.
