ignoreOriginUrl: add initial support of ignore lists

Add the ability to specify hosts and patterns lists to ignore the given
entry url and replace it with the fetched content url without touching
to origin_url.

This initial support should be reworked in the following months to move
the hardcoded ignore lists in the database.
