Corrects service URLs from "%s/%s/" to "%s/%s"

Reasons:
- "%s/%s/" adds extra / making it "//" whenever it goes to the resources
  like nova or heat or cinder.
- Though it was working fine for nova and cinder, but following recent
  changes on heat/heat-client this is giving an error:
  "The resource could not be found.".

Changes:
- Updates the URLs from "%s/%s/" to "%s/%s".
