Adding a XD acceptance test using SMB SR

This is an attempt to run the existing XD acceptance test suite on SMB SR.

The catch is that the site SC03 is not configured with SMB Shares. Hence for now we may have to use its adjacent site SC04 provided SMB share. This may have an impact as the large amount of data go through the router between SC03 and SC04 controller.

Also, for now, my intension is to run on a smaller set of 4 hosts with 20 guests each. Let me know how it sounds?
