Add cookie token extractor

[tnucera]

Hi,

We store the token in a cookie (secure and httponly) in onAuthenticationSuccess like this :

    public function onAuthenticationSuccess(Request $request, TokenInterface $token)
    {
        $response = parent::onAuthenticationSuccess($request, $token);

        $tokenJWT = json_decode($response->getContent(), true)['token'];

        // Ajoute le token avec l'id de l'utilisateur en clé dans les Redis configurés, avec le ttl contenu dans la conf
        $this->rms->set($this->redisDB, $token->getUser()->getId(), $tokenJWT, $this->jwtTokenTTL);

        // Crée le cookie contenant le token, avec le ttl contenu dans la conf
        $response->headers->setCookie(new Cookie('CERBERE', $tokenJWT, (new \DateTime())->add(new \DateInterval('PT' . $this->jwtTokenTTL . 'S')), '/', null, $this->cookieSecure));

        return $response;
    }

Cookie is send transparently from Front to Back.
So we need a cookie token extractor.

Thanks

Hi,

Nice addition ! Just replace the short array syntax with the classic one for PHP 5.3.

Also, could you squash you commits into a single one ? And what do you think about giving the default cookie name the same as the query parameter ?

Thanks.

Replace with classic array syntax for PHP 5.3 compatibility.

Ok it's done.
For the same name as the query parameter, it's more a thinking to have about the global conf of the bundle.
Indeed, there is code duplication in the factory at this level.
Why not just have (or something like this) :

            extractors:
                enabled: ['authorization_header', 'cookie', 'query_parameter']
                name:     Bearer

That's a good idea. In the mean time, let's merge this PR.
