creating l3 vmotion with powercli and csv

So sometimes the shortcomings of my vtool at 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.
