[SPARK-16498][SQL][WIP] move hive hack for data source table into
HiveExternalCatalog
## What changes were proposed in this pull request?
Spark SQL doesn't have its own meta store yet, and use hive's currently.
However, hive's meta store has some limitations(e.g. columns can't be too many,
not case-preserving, bad decimal type support, etc.), so we have some hacks to
successfully store data source table metadata into hive meta store, i.e. put
all the information in table properties.
This PR moves these hacks to `HiveExternalCatalog`, tries to isolate hive
specific logic in one place.
It's based on https://github.com/apache/spark/pull/14071
## How was this patch tested?
existing tests.
