Add VLAN tagging to COS and VMkernel portgroup

I had need to tag the service console and vmkernel portgroups well after the fact of building a bunch of ESX server.  It’s actually pretty easy to do.  Command is: esxcfg-vswitch -p <Portgroup Name> -v <VLAN ID> <vSwitch Name>

`esxcfg-vswitch -p Service Console -v 999 vSwitch0`

From there the easy way of change the VMkernel port is via the GUI.
