[FLINK-8328] [flip6] Move Yarn ApplicationStatus polling out of
YarnClusterClient
## What is the purpose of the change
Introduce YarnApplicationStatusMonitor which does the Yarn
ApplicationStatus polling in
the FlinkYarnSessionCli. This decouples the YarnClusterClient from the
actual communication
with Yarn and, thus, gives a better separation of concerns.

- Decouple `YarnClusterClient` from Yarn `ApplicationStatus` polling

> Project: Flink
> Issue Type: Improvement
> Components: Client
> Affects Versions: 1.5.0
> Reporter: Till Rohrmann
> Assignee: Till Rohrmann
> Labels: flip-6
> Fix For: 1.5.0
>
>
> In order to make the {{FlinkYarnSessionCli}} work with Flip-6, we have to
> pull the Yarn {{ApplicationStatus}} polling out of the {{YarnClusterClient}}.
> I propose to introduce a dedicated {{YarnApplicationStatusMonitor}}. This has
> also the benefit of separating concerns better.
