swagger: scope pattern requires a space

[pnicolcev-tulipretail]

The pattern definition for scope in the client requires a space after each scope. This is causing problems when generating a client that checks against this pattern.

https://github.com/ory/hydra/blob/master/client/client.go#L57

I've generated a PHP client and so far it works, but when creating a client I get errors when the scope is returned.

For reference, the generated code:

     /**
      * Sets scope
      * @param string $scope Scope is a string containing a space-separated list of scope values (as described in Section 3.3 of OAuth 2.0 [RFC6749]) that the client can use when    requesting access tokens.
      * @return $this
      */
     public function setScope($scope)
     {

         if (!is_null($scope) && (!preg_match("/([a-zA-Z0-9\\.\\*]+\\s)+/", $scope))) {
             throw new \InvalidArgumentException("invalid value for $scope when calling OAuth2Client., must conform to the pattern /([a-zA-Z0-9\\.\\*]+\\s)+/.");
         }

         $this->container['scope'] = $scope;

         return $this;
     }

Changing it to /([a-zA-Z0-9\\.\\*]+\\s?)+/ resolves the issue.

Am I reading this correctly? Want a PR?

Ah yes, because if only one scope is allowed, that won't match. Feel free to create a PR!

This is resolved now
