VMware PowerCLI - Creating Standard Virtual Switches and updating VM Network Adapter Labels

In preparation to migrate ESXi hosts from one VMware vCenter 5.0 server to another VMware vCenter 5.5 server, I created this script to automate re-configuring the VM network labels to use a standard vSwitch on each ESXi server.  The script connects to the vCenter server and creates a new standard vSwitch on each ESXi host as well as assigns an available physical uplink (vmnic).  Then also creates the portgroups for each VLAN, and finally updates the VMs network lables in a given cluster.
