[SPARK-17358][SQL] Cached table(parquet/orc) should be shard between
beelines
## What changes were proposed in this pull request?
Cached table(parquet/orc) couldn't be shard between beelines, because the
`sameResult` method used by `CacheManager` always return false when compare two
`HadoopFsRelation` in different beelines. So I override the `equals` and
`hashCode` in `HadoopFsRelation`.(Just compare the locations)
## How was this patch tested?
