Encrypt migration credentials at rest (#15895)
* encrypt migration credentials in task persistence

Not sure this is the best approach, we could encrypt the entire
`PayloadContent` instead. Also instead of clearing individual fields in
payload content, we could just delete the task once it has
(successfully) finished..?

* remove credentials of past migrations

* only run DB migration for completed tasks

* fix binding

* add omitempty

* never serialize unencrypted credentials

* fix import order
