Allow addition of extra entity classes for VKey conversion (#877)

* Allow addition of extra entity classes for VKey conversion

This allows us to create VKeys from Keys for test objects that may not
be part of the original codebase.

This isn't used anywhere directly yet but it will be useful in the
future when testing the replay of SQL transactions.
