chore(prepopulation): Move prepopulation files on features/prepopulate_p...

...rofiles
My comment was related to the fact that with a config there is no need to move the files around, I think at least from SDX perspective is better/cleaner to have them in the apps folder where are at the moment than to pollute the root folder.
Either way if no one else has an issue with this I'm good with the proposed changes.
