Support https proxy

[hvanoch]

We are experiencing the same issue as described here: #1025
We did found the cause and solution.

This happens when proxing an https for a http request.
In

platform/src/Oro/Bundle/SecurityBundle/Resources/config/services.yml

Line 744 in 3475755

oro_security.csrf_token_manager:

The thirth parameter is not configured. If you provide the request_stack service it will actually check if https is used with the symfony request, instead of the PHP $_SERVER variable. The symfony request has checks that validate if the request is being used by a proxy.
So changing it from:

    oro_security.csrf_token_manager:
        class: Symfony\Component\Security\Csrf\CsrfTokenManager
        public: false
        arguments:
            - '@security.csrf.token_generator'
            - '@oro_security.csrf.cookie_token_storage'

to

    oro_security.csrf_token_manager:
        class: Symfony\Component\Security\Csrf\CsrfTokenManager
        public: false
        arguments:
            - '@security.csrf.token_generator'
            - '@oro_security.csrf.cookie_token_storage'
            - '@request_stack'

Fixes the issue.

The symfony class that is used looks like.

    public function __construct(TokenGeneratorInterface $generator = null, TokenStorageInterface $storage = null, $namespace = null)
    {
        $this->generator = $generator ?? new UriSafeTokenGenerator();
        $this->storage = $storage ?? new NativeSessionTokenStorage();

        $superGlobalNamespaceGenerator = function () {
            return !empty($_SERVER['HTTPS']) && 'off' !== strtolower($_SERVER['HTTPS']) ? 'https-' : '';
        };

        if (null === $namespace) {
            $this->namespace = $superGlobalNamespaceGenerator;
        } elseif ($namespace instanceof RequestStack) {
            $this->namespace = function () use ($namespace, $superGlobalNamespaceGenerator) {
                if ($request = $namespace->getMainRequest()) {
                    return $request->isSecure() ? 'https-' : '';
                }

                return $superGlobalNamespaceGenerator();
            };
        } elseif (\is_callable($namespace) || \is_string($namespace)) {
            $this->namespace = $namespace;
        } else {
            throw new InvalidArgumentException(sprintf('$namespace must be a string, a callable returning a string, null or an instance of "RequestStack". "%s" given.', get_debug_type($namespace)));
        }
    }
