Permanent redirect feature added

closes #5104

[humitos]

I like these changes. They allow us to give a custom solution for a particular request without breaking anything and not exposing users with a dangerous redirect.

Users can request a 301 redirect via our support queue and we just need to make a change on those redirects after they set them up and are happy.

I'm requesting for another review from the @rtfd/core team to be sure that this is the first step to support this.

Looks good to me. I think we could expose this to users over time, but modeling it is the first step 👍

Should we add a migration to change all the existing 301 redirects to 302?

@davidfischer this PR has a migration to change all existing 301 redirects to 302

[davidfischer]

Ahhh, I missed that part of the migration. I saw that there was one migration and I assumed it was auto-generated. However, I now see that changing the default and setting all the ones in the DB is in one migration. Thanks.

I want to make the redirects and all future redirects in my project 301. I sent an email and no positive response yet.

When can we get the option to to do this ourselves?

@w3guy Hi! I sent you an email yesterday with a question and today I made your redirects 301. Please, keep talking over email. There is no need to comment on a closed PR to ask for support 😃 Thanks!
