> It'd be easier to debug things like MapReduce and Spark jobs if our 
> AuthenticationTokenIdentifier provided a toString method.
> For comparison, here's an example of a MapReduce job that has both an HDFS 
> delegation token and our delegation token:
> {code:java}
> 18/02/21 20:40:06 INFO mapreduce.JobSubmitter: Kind: HBASE_AUTH_TOKEN, 
> Service: 92a63bd8-9e00-4c04-ab61-da8e606068e1, Ident: 
> (org.apache.hadoop.hbase.security.token.AuthenticationTokenIdentifier@17)
> 18/02/21 20:40:06 INFO mapreduce.JobSubmitter: Kind: HDFS_DELEGATION_TOKEN, 
> Service: 172.31.118.118:8020, Ident: (token for some_user: 
> HDFS_DELEGATION_TOKEN owner=some_u...@example.com, renewer=yarn, realUser=, 
> issueDate=1519274405003, maxDate=1519879205003, sequenceNumber=23, 
> masterKeyId=9)
> {code}
> Stuff in TokenIdentifier is supposed to be public, so we should be fine to 
> dump everything, similar to Hadoop's AbstractDelegationTokenIdentifier.
