Include buildDate and scanDate in VAT import

Background

Currently, the import only receives a "timestamp" which represents both the build date and the scan date. This has been sufficient since we always built right before scanning. In the near future, we wish to be able to re-scan old builds. VAT import needs two fields added to the import call. The "buildDate" and the "scanDate" so that proper logic can be implemented. We will still need to provide timestamp in the import after implementing this until VAT deprecates it.
