MULTISITE_CMS_URLS used in the first migration

[lcfd]

enhancement proposal

If there are no sites in Home › Sites › Sites or there's only example.com during the initial migration insert the values in MULTISITE_CMS_URLS as the starting Sites .

I find this useful in the deploy phase.

I would prefer an explicit (and documented) management command to handle this. I don't like data creation by "automagic"
I'm 👍 on adding a command

[lcfd]

Explicit is better than implicit. they said :)

A command is a good idea, but I also suggest to add a warning somewhere, because is the error is a little bit cufusing
