Don't assume encrypted message response
Don't assume encrypted message response

 - OMI server prefers to not send spnego encrypted messages
   when the transport is SSL.

   The WinRM gem prefers to always send spnego messages,
   regardless of HTTP or HTTPS transport.

 - When responses are received, verify their content type
   before trying to decrypt. If the messages are already
   application/soap+xml, return the body content
