Provide documentation for Symfony4

[polishExperiment]

This is feature request.

Symfony 4.x

Currently there is no documentation for Symfony 4.

This issue is an attempt at fixing that.

[polishExperiment]

Could someone put me as an assignee? Could someone put a label Documentation or give me access to do that myself?

I've configured successfully the bundle in Symfony 4 the changes needed are

• On src/Entity/User.php change the namespace form

  namespace AppBundle/User;

  to

  namespace App\Entity;

• The configuration needs to be in its own file Create a new file called config/packages/fos_user_bundle.yml

  fos_user:
  db_driver: orm # other valid values are 'mongodb' and 'couchdb'
  firewall_name: main
  user_class: App\Entity\User  # <--- Note the namespace must be App not AppBundle
  from_email:
      address: "%env(MAILER_ADDRESS)%"
      sender_name: "%env(MAILER_SENDER_NAME)%"

• On security.yml there is a problematic field I had the same issue as #2855 so

              user_checker: fos_user.user_checker

  needs to be changed to

              user_checker: security.user_checker

  seems to work after this change, but I'm not sure this is 100% correct as @xabbuh points out in the below PR fos_user.user_checker is still defined in security.yml file of the bundle.
  https://github.com/FriendsOfSymfony/FOSUserBundle/pull/2867 Also it would be needed to add a new element in the dropdown to point to version 4 on the Symfony documentation site

Also required:

You've to add the following to the config/packages/framework.yaml:

framework:
    # ... other stuff ...

    templating:
        engines: ['twig', 'php']

Right now the Official Symfony website is displaying this warning,

One suggestion @XWB, I think that we need to create a 4.x branch and then we can open a pull request with the updated documentation, master and 4.x can be the same, but I suspect that Symfony website convention is to read from version number branch to match their dropdown switcher for versions.
Also, it would be great to have a label for Symfony 4 to group all related issues, specially for newcomers.

Thanks you!

@XWB any update with this? Could you create the branch 4.x as suggested by @alfonsodev ?
