Support S3 server-side redirects

Just an idea :)

This is actually quite interesting @tomdyson thanks! Although you force the user to use S3 (it's an option now). I'll contact the guys from django-bakery, there are some ideas to make adapters (like azure storage, etc.). This will be a great addition to that!

Yeah, we rolled our own for use with Wagtail...

def create_s3_redirects(self):
    self.stdout.write('Creating redirects')
    site = Site.objects.filter(is_default_site=True).first()
    redirects = Redirect.objects.all()
    for r in redirects:
        old_path = r.old_path[1:]  # strip leading /
        self.stdout.write(old_path)
        dest_url = r.redirect_link
        if r.redirect_page:
            dest_url = r.redirect_page.specific.relative_url(
                r.site or site
            )
            dest_url = settings.BASE_URL + dest_url
        self.create_s3_redirect(old_path, dest_url)

def create_s3_redirect(self, old_path, dest_url):
    self.s3.meta.client.put_object(Bucket=settings.AWS_STORAGE_BUCKET_NAME,
                                   Key=old_path,
                                   WebsiteRedirectLocation=dest_url)

So if you implement the adapter idea, there'd be a method to create redirects and those backends that couldn't do redirects could just stub it out.

Awesome @dprothero. However support for Redirects is missing now actually in this module. A separate RedirectView with a get_queryset set to all Wagtail redirects (which renders the redirect html templates) would also work for some people.
