[FLINK-8787][flip6] Deploying FLIP-6 YARN session with HA fails
## What is the purpose of the change
*Deploying FLIP-6 YARN session with HA fails because the ZooKeeper
namespace is not set correctly. The namespace is `/flink/default` but it should
include the YARN application id.*
cc: @tillrohrmann
## Brief change log
- *Use defensive copies of `Configuration` objects in
`AbstractYarnClusterDescriptor`. Never modify existing configuration.*
- *Ensure that zk namespace configuration reaches RestClusterClient*
## Verifying this change
This change added tests and can be verified as follows:
- *Manually deployed Flink on YARN with HA enabled.*
