> Remove netty-router dependency

> Key: FLINK-9386
> URL: https://issues.apache.org/jira/browse/FLINK-9386
> Project: Flink
> Issue Type: Sub-task
> Reporter: Piotr Nowojski
> Assignee: Piotr Nowojski
> Priority: Major
> Fix For: 1.6.0
>
>
> netty-router 1.10 blocks upgrade to 4.1, while netty-router 2.2.0 has broken
> compatibility in a way that it's unusable by us (it doesn't allow to sort
> router paths as in https://issues.apache.org/jira/browse/FLINK-8000 ). I
> propose to copy & simplify & modify netty-router code to suite our needs.
