This ticket removes the restriction on version 3.0 of the Ldap component, as the component is now both backward and forward-compatible.

This PR is being made against the `3.0` branch and not in the `2.8` branch as it seems that all other dependencies rely on `~2.8|~3.0.0` for the `2.8` branch.

There will be a conflict with the `master` branch. The versions to use on the `master` branch is `~3.1` for both `composer.json` files, as the authentication provider and the user provider rely on the new interface, and the `LdapInterface::query()` method, instead of `LdapClientInterface::search()`, which is deprecated.
