note, we do want env var eval on the launcher cli

> Key: YARN-11454

> Project: Hadoop YARN
> Issue Type: Bug
> Components: client, yarn
> Affects Versions: 3.3.4
> Reporter: Steve Loughran

> Fun one. ABFS proxy settings come through sysprops not hadoop conf options,
> so have to bse set in one of the various .java.opts config options -for am
> and workers.
> Except with all the layers in the way, there are some corner cases of char
> which don't make it through. And the default solution "don't do that" comes
> up against central IT policies of "no can do"
> Fix: work out what the brittle chars are escape so that launcher doesn't get
> the clever idea to join in.
