[SPARK-18840][YARN] Avoid throw exception when getting token renewal interval in non HDFS security environment
## What changes were proposed in this pull request?
Fix `java.util.NoSuchElementException` when running Spark in non-hdfs security environment.
In the current code, we assume `HDFS_DELEGATION_KIND` token will be found in Credentials. But in some cloud environments, HDFS is not required, so we should avoid this exception.
## How was this patch tested?
Manually verified in local environment.
