[SPARK-14912][SQL] Propagate data source options to Hadoop configuration
## What changes were proposed in this pull request?
We currently have no way for users to propagate options to the underlying
library that rely in Hadoop configurations to work. For example, there are
various options in parquet-mr that users might want to set, but the data source
API does not expose a per-job way to set it. This patch propagates the
user-specified options also into Hadoop Configuration.
## How was this patch tested?
Added a unit test to test both the read path and the write path.
