* Remove leading module parameter on open_url call as it's no longer used
by module_utils.urls.open_url

Due to a software bug in vSphere, it fails to handle ampersand in datacenter names.
The solution is to do what vSphere does (when browsing) and double-encode ampersands.
It is likely other characters need special treatment like this as well, haven't found any.
