Easier configuration of automatic redirects

[loevgaard]

Right now the automatic redirect feature is maybe too complicated: It involves form extensions and javascript. What if we could just enable it by config like so:

setono_sylius_redirect:
    automatic_redirects:
        - 'sylius.product_translation'
        - 'sylius.taxon_translation'

where sylius.product_translation and sylius.taxon_translation are the resources defined by Sylius.

Of course this would create more redirects than necessary, but if people have implemented the cronjob to remove redirects that aren't accessed, that wouldn't be a problem.
