[FLINK-8328] [flip6] Move Yarn ApplicationStatus polling out of
YarnClusterClient
## What is the purpose of the change

ApplicationStatus polling in
the FlinkYarnSessionCli. This decouples the YarnClusterClient from the
actual communication
with Yarn and, thus, gives a better separation of concerns.
