Special notes for your reviewer:
speed up resource migration, the resource migration framework previously needed to execute 3 SQL statements for each record migration:
Step 1 and step 3 is not necessary.
If a record allows duplicates, we don't have to do step 1, and we can insert the record regardless of whether they already exist.
We can get generated keys by jdbc directly rather than query it.
Added transaction control in
ResourceMigrator
