GEODE-4833: JdbcWriter and JdbcAsyncWriter may fail to write null fields to database (#1636)

Null values are now supported. Meta-data read from the database is now used to determine the
column type and used to call setNull.

* Renamed TableKeyColumnManager to TableMetaDataManager
* registerPdxMetaData will now throw an exception if the instance is not serialized with PDX

> Both JdbcWriter and JdbcAsyncWriter end up calling the JDBC method PreparedStatement.setObject with a value of "null" if the pdx field contains "null".
> This will work with jdbc drivers that support sending "non-typed Null" to the backend database.
> But some drivers do not support this and these puts will fail with a SQLException.
> For portability the jdbc connector should be changed to not pass "null" to setObject without a type.
