move FOSRestBundle + FOSUserBundle docs to symfony.com

[lsmith77]

I am wondering if we should move the docs for FOSRestBundle and FOSUserBundle to symfony.com. In fact I guess it would make sense to push for moving the docs for lets say the top 10-20 Bundles over to symfony.com in the long run.

if documentations about bundles are pushed into symfony.com it might mean they get official support from sensio which is not the case. Also this can be confusing to have a sonata-project.org website or a cmf-project.org website without documentations.

We can safely close this issue because it's closely related to #3164 and we are well aware of this improvement. In fact, the bundles section is going to be revamped by Fabien, but we need more time to carefully think about how to do it.
