[SPARK-17319] [SQL] Move addJar from HiveSessionState to HiveExternalCatalog
### What changes were proposed in this pull request?
This is another step to remove Hive client usage in `HiveSessionState`.
Different sessions are sharing the same class loader, and thus,
`metadataHive.addJar(path)` basically loads the JARs for all the sessions.
Thus, no impact is made if we move `addJar` from `HiveSessionState` to
`HiveExternalCatalog`.
