[4.x] Field based redirects may provide a status

[ryanmitchell]

This PR adds the ability to choose whether a redirect from the 'Link' blueprint is a 301 or a 302 redirect.

Closes statamic/ideas#1118

I started tweaking the code and then we talked about it a little here and came up with some more changes.

Could you please:

• Remove the redirect_status field.
• Make redirect into a group field containing url and status fields. (We preferred if there was still just a single field)
• Make the url sub-field 100% wide
• Make the status sub-field a 100% width radio with inline: true (The select was a bit cramped)
• Tweak DataResponse@getRedirect so that:
  • If the value is an array (via the group fieldtype), it gets the url and status from the sub-values.
  • If the value is a string, it uses that like it always has. Assume a 302 status.

No problem. I’ll work on it tomorrow 👍

@jasonvarga thats done. You'll see there were a few other tweaks required to queries and elsewhere in ResolveRedirect

[jasonvarga]

Awesome. Thank you.
