[SPARK-19678][SQL] remove MetastoreRelation
## What changes were proposed in this pull request?
`MetastoreRelation` is used to represent table relation for hive tables,
and provides some hive related information. We will resolve
`SimpleCatalogRelation` to `MetastoreRelation` for hive tables, which is
unnecessary as these 2 are the same essentially. This PR merges
`SimpleCatalogRelation` and `MetastoreRelation`
## How was this patch tested?
