[SPARK-17970][SQL][WIP] store partition spec in metastore for data source
table
## What changes were proposed in this pull request?
We should follow hive table and also store partition spec in metastore for
data source table.
This brings 2 benefits:
1. It's more flexible to manage the table data files, as users can use `ADD
PARTITION`, `DROP PARTITION` and `RENAME PARTITION`
2. We don't need to cache all file status for data source table anymore.
## How was this patch tested?
existing tests.
