Deletes Router accounts just created.

This method runs as a cleanup after something goes wrong. Its purpose is to undo CREATE USER [IF NOT EXISTS] for accounts that got created during bootstrap. Note that it will drop only those accounts which did not exist prior to bootstrap (it may be a subset of account names passed to CREATE USER [IF NOT EXISTS]). If it is not able to determine what this (sub)set is, it will not drop anything - instead it will advise user on how to clean those up manually.
