global setting is not useful from vCenter 5.0 onwards
URL: https://github.com/apache/cloudstack/pull/1253#issuecomment-387360970
 
 
   There is an issue with existing environments, which may be using dvsportgroups.  If portgroup
has more than (say) 8 ports in use already then a error such as:
   `Cannot set number of ports to 10 because at least 11 out of 18 ports are still in use`
   will be thrown when creating a VM on said switch and the VM will fail to be deployed.
   Setting ALL dvsportgroups to use a sufficiently high number will be expensive in large
environments.
   
   Code needs to set number of ports to slightly higher than the number of ports in use, on
a per  portgroup basis.

> CloudStack has a global config paramter vmware.ports.per.dvportgroup for setting the
number of ports per dvportgroup of Distributed Virtual Switch (DVS) and this takes effect
when the zone is created.
> Auto expand/shrink features adjusts the ports per dvportgroup value dynamically from
ESX 5.0 release. So, even if we set this global setting, auto expand will take effect and
the value configured at cloudstack is not useful anymore.
