[SPARK-10035][SQL] Parquet filters does not process EqualNullSafe filter.
As I talked with Lian,
1. I added EquelNullSafe to ParquetFilters
- It uses the same equality comparison filter with EqualTo since the
Parquet filter performs actually null-safe equality comparison.
2. Updated the test code (ParquetFilterSuite)
- Convert catalyst.Expression to sources.Filter
- Removed Cast since only Literal is picked up as a proper Filter in
DataSourceStrategy
- Added EquelNullSafe comparison
3. Removed deprecated createFilter for catalyst.Expression
