SSH remoting is measureably slower than WSMan remoting #2852
Description
Expected SSH to be on par or faster than WSMan as we no longer have to deal with SOAP/XML encoding

The current code is built around base64 encoding which is not necessary for SSH. The changes will be intensive to avoid breaking WSMan remoting.

We should also consider a binary serializer than using the current xml serializer
