Summary0004064: Allow zero date on MySQL or convert to null otherwise
DescriptionAdd a database info property for "zero date allowed" and default it to false. Only MySQL appears to allow a zero date, so that platform will set the property to true. For other databases, convert the zero date to a null so the row can load. Since the conversion will happen during loading, the user still has the option of configuring a transform to handle zero dates in another way.

Some background info: the Java conversion of a string 0000-00-00 00:00:00 to timestamp object fails because there is no year 0 on the calendar. There is a second operation on failure where tries again and it's able to format the date, but returns the closest valid date of 0002-11-30. By setting the parameter of for a MySQL node, the zero date can be loaded because no conversion is done in Java. Also, the db.url parameter needs modified to remove the zeroDateTimeBehavior=convertToNull URL parameter -- that parameter only affects queries and initial load, while triggers capture zero dates regardless.
