[SPARK-13754] Keep old data source name for backwards compatibility
## Motivation
CSV data source was contributed by Databricks. It is the inlined version of
https://github.com/databricks/spark-csv. The data source name was
`com.databricks.spark.csv`. As a result there are many tables created on older
versions of spark with that name as the source. For backwards compatibility we
should keep the old name.
## Proposed changes
`com.databricks.spark.csv` was added to list of `backwardCompatibilityMap`
in `ResolvedDataSource.scala`
## Tests
A unit test was added to `CSVSuite` to parse a csv file using the old name.
