add dnsjava to solve NoDefClassException

[huayucai]

What changes were proposed in this pull request?

when setting "hadoop.security.token.service.use_ip=false" in core-site.xml (configuration in hadoop) ,we encounter a NoClassDefFoundError of "Could not initialize class org.apache.hadoop.security.SecurityUtil". It is caused by lacking a dependency of dnsjava. We have already tested that it affects ranger-admin、ranger-kms、ranger-usersync、ranger-kafka-plugin. When start up the server,the problem will be seen.

How was this patch tested?

After using maven to build project, the jar 'dnsjava-xxx.jar' should be added to the package
