[SPARK-24149][YARN][FOLLOW-UP] Add a config to control automatic namespaces
discovery
## What changes were proposed in this pull request?
Our HDFS cluster configured 5 nameservices: `nameservices1`,
`nameservices2`, `nameservices3`, `nameservices-dev1` and `nameservices4`, but
`nameservices-dev1` unstable. So sometimes an error occurred and causing the
entire job failed since
[SPARK-24149](https://issues.apache.org/jira/browse/SPARK-24149):

I think it's best to add a switch here.
## How was this patch tested?
