allow setting target host for vm

[alclonky]

allows loadbalancing vms on the esx hosts

we are using it like

...

(1..30).each do |i|
  config.vm.define "client-#{i}" do |client|
    client.vm.provider "vsphere"
    client.vm.provider :vsphere do |vsphere|
      vsphere.name = "client-#{i}"
      if i.even?
        vsphere.target_host = 'esxhost1'
      else
        vsphere.target_host = 'esxhost2'
      end
    end
  end
end

...
