creating l3 vmotion with powercli and csv

So sometimes the shortcomings of my vtool at github.com/mrambig/vmware/vtool is that it assumes that the ip addresses are in range when creating vmkernel portgroups for vmware. It also assumes that your hosts are in order. We are working a huge VMware implementation which is being deployed and expanded in installment where this is not the case. This is something that i putting it here for those who might use this in future. Of course i have to still test this with my solution architects for whom I am doing this automation. I am certain that it will work. If not I will post the updated version as always in my github page. github.com/MrAmbiG/vmware
