Attaching direct org network to `vcd_vapp_vm` with incorrect IP gives non informative error

[Didainius]

Attaching direct org network to vcd_vapp_vm with incorrect IP gives non informative error.

Such HCL definition

resource "vcd_vapp_vm" "web1" {
  # ...
  network {
    type               = "org"
    name               = vcd_vapp_org_network.direct-net.org_network_name
    ip                 = "10.10.104.161"
    ip_allocation_mode = "MANUAL"
  }
}

Will result in such error if ip address does not actually belong to direct network.

vcd_vapp_vm.web1: Still creating... [10s elapsed]

  on vcd.TestAccVcdVAppVm_Basic.tf line 115, in resource "vcd_vapp_vm" "web1":

Such error handling needs improvement
