TACHYON-198 Move UserConf usage to use TachyonConf

This PR consist next steps to integrate new configuration work:
-) Remove usage of UserConf
-) Push TachyonConf to Tachyon Hadoop's file system (aka TFS class).
-) Remove UserConf.java from repo.
Most of tachyon follows access from methods rather than fields. There is
also a history of changing code from field access to method access. This
means that this code follows a minority in style
