title: How do I force zeep to use only TLSv1.2?
body: <p>I'm designing a SOAP client using python and SOAP server I'm connecting to only allows TLSv1.2. I looked up in <code>zeep</code> documentation but couldn't find any setting where I can force it to use only 'TLSv1.2'. If zeep doesn't have this feature, are there any other SOAP python libraries with this feature ?</p>
