Avoid redundant calls for tokens in TokenCache

Key: MAPREDUCE-3850

Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: security
Affects Versions: 0.23.1, 0.24.0
Reporter: Daryn Sharp
Assignee: Daryn Sharp
The {{TokenCache}} will repeatedly call the same filesystem for tokens. This
is inefficient and can easily be changed to only call each filesystem once.
