Support Redirect Domain module redirects

Re-rolled and updated patch against 2.0.7

Hi!

Thank you for your efforts in this issue.

I believe this is a very specific use case and I believe would be better to consider this as a separate contrib module depending on this one.

Feel free to reopen if you think different and we can discuss a different approach.

Patch against version 2.0.9

Updated patch to fixType Error in MigrateRedirectForm
