Add cloudstack_physicalnetwork and some underlying additional resources

[ianc769]

Adding cloudstack_physicalnetwork , cloudstack_traffic_type and cloudstack_physicalnetwork as terraform managed resource options:

cloudstack_physicalnetwork -> https://cloudstack.apache.org/api/apidocs-4.20/apis/createPhysicalNetwork.html

cloudstack_traffic_type -> https://cloudstack.apache.org/api/apidocs-4.20/apis/addTrafficType.html

cloudstack_network_service_provider -> https://cloudstack.apache.org/api/apidocs-4.20/apis/addNetworkServiceProvider.html

Using this code for example:

resource "cloudstack_zone" "foo" {
  name          = "terraform-zone"
  dns1          = "8.8.8.8"
  internal_dns1 = "8.8.4.4"
  network_type  = "Advanced"
}

resource "cloudstack_physicalnetwork" "foo" {
  name                   = "terraform-physical-network"
  zone                   = cloudstack_zone.foo.name
  broadcast_domain_range = "ZONE"
  isolation_methods      = ["VLAN"]
}

resource "cloudstack_traffic_type" "foo" {
  physical_network_id = cloudstack_physicalnetwork.foo.id
  type                = "Management"
  kvm_network_label   = "cloudbr0"
}

resource "cloudstack_network_service_provider" "securitygroup" {
  name                = "SecurityGroupProvider"
  physical_network_id = cloudstack_physicalnetwork.foo.id
  state               = "Enabled"
}

  # cloudstack_network_service_provider.securitygroup will be created
  + resource "cloudstack_network_service_provider" "securitygroup" {
      + id                  = (known after apply)
      + name                = "SecurityGroupProvider"
      + physical_network_id = (known after apply)
      + state               = "Enabled"
    }

  # cloudstack_physicalnetwork.foo will be created
  + resource "cloudstack_physicalnetwork" "foo" {
      + broadcast_domain_range = "ZONE"
      + id                     = (known after apply)
      + isolation_methods      = [
          + "VLAN",
        ]
      + name                   = "terraform-physical-network"
      + zone                   = "terraform-zone"
    }

  # cloudstack_traffic_type.foo will be created
  + resource "cloudstack_traffic_type" "foo" {
      + id                  = (known after apply)
      + kvm_network_label   = "cloudbr0"
      + physical_network_id = (known after apply)
      + type                = "Management"
    }

  # cloudstack_zone.foo will be created
  + resource "cloudstack_zone" "foo" {
      + allocationstate = (known after apply)
      + dns1            = "8.8.8.8"
      + id              = (known after apply)
      + internal_dns1   = "8.8.4.4"
      + name            = "terraform-zone"
      + network_type    = "Advanced"
    }
