Add WS-I Compliant QuotedSoapActionMiddleware

[veewee]

The default SOAP client does not guarantee compatibility with the WS-I basic profile.
This middleware ensures that the action inside the SOAPAction header is wrapped with double quotes as specified in rule R2744.

Usage

use \Phpro\SoapClient\Middleware\WSICompliance\QuotedSoapActionMiddleware;

$wsdlProvier = HttPlugWsdlProvider::create($client);
$wsdlProvider->addMiddleware(new QuotedSoapActionMiddleware());
