This branch add request.redirect on all requests.
In case of a front end request, we do an url_for to the location.

We removed redirect_with_hash that was only for retro compatibility

local_redirect has been renamed to redirect_query, and param keep_hash has been
removed and moved.

Default code for redirect is 303 now instead of 302.

Now redirect and redirect_query make local redirect by default, you need to
pass local=False to make external redirect.

All werkeug.utils.redirect has been replaced by request.redirect.

Http.redirect now use an http.Response type, and it become easy to add an
override like 'set_cookies' e.g.

Dispatch of a website.page return an http.response too, so we first need to
check if it is a cached version before to check if it is an Odoo Response.

Migrate your code:

http.redirect -> request.redirect(location, code, local)
http.local_redirect -> request.redirect_query(location, query, code, local)
http.redirect_with_hash -> request.redirect
