Platform:

• Azure IPI

What happened?
When one creates an IPI Azure cluster with an `internal` publishing method, it creates a standard load balancer with an empty definition. This load balancer doesn't serve a purpose as far as I can tell since the configuration is completely empty. Because it doesn't have a public IP address and backend pools it's not providing any outbound connectivity, and there are no frontend IP configurations for ingress connectivity to the cluster.

Below is the ARM template that is deployed by the installer (through terraform)

```
{
"$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"loadBalancers_mgahagan411_7p82n_name":

{ "defaultValue": "mgahagan411-7p82n", "type": "String" }

},
"variables": {},
"resources": [
{

"apiVersion": "2020-11-01",
"name": "[parameters('loadBalancers_mgahagan411_7p82n_name')]",
"location": "northcentralus",
"sku":

{ "name": "Standard", "tier": "Regional" }

,
"properties":

{ "frontendIPConfigurations": [], "backendAddressPools": [], "loadBalancingRules": [], "probes": [], "inboundNatRules": [], "outboundRules": [], "inboundNatPools": [] }

}
]
}
```

What did you expect to happen?

• Don't create the standard load balancer on an internal Azure IPI cluster (as it appears to serve no purpose)

How to reproduce it (as minimally and precisely as possible)?
1. Create an IPI cluster with the `publish` installation config set to `Internal` and the `outboundType` set to `UserDefinedRouting`.
```
apiVersion: v1
controlPlane:
architecture: amd64
hyperthreading: Enabled
name: master
platform:
azure: {}
replicas: 3
compute:

• architecture: amd64
  hyperthreading: Enabled
  name: worker
  platform:
  azure: {}
  replicas: 3
  metadata:
  name: mgahaganpvt
  platform:
  azure:
  region: northcentralus
  baseDomainResourceGroupName: os4-common
  outboundType: UserDefinedRouting
  networkResourceGroupName: mgahaganpvt-rg
  virtualNetwork: mgahaganpvt-vnet
  controlPlaneSubnet: mgahaganpvt-master-subnet
  computeSubnet: mgahaganpvt-worker-subnet
  pullSecret: HIDDEN
  networking:
  clusterNetwork:
• cidr: 10.128.0.0/14
  hostPrefix: 23
  serviceNetwork:
• 172.30.0.0/16
  machineNetwork:
• cidr: 10.0.0.0/16
  networkType: OpenShiftSDN
  publish: Internal
  proxy:
  httpProxy: http://proxy-user1:password@10.0.0.0:3128
  httpsProxy: http://proxy-user1:password@10.0.0.0:3128
  baseDomain: qe.azure.devcluster.openshift.com
  ```

2. Show the json content of the standard load balancer is completely empty
`az network lb show -g myResourceGroup -n myLbName`

```
