Adding VirtualRouterAutoScaleConfiguration for Route Server

[ksteinmeyer2023]

1. Resource provider. What is the Azure resource provider your feature is part of?

Microsoft.Network

2. Description of feature or work requested. Provide a brief description of the feature or work requested. A link to conceptual documentation may be helpful too.

Add the VirtualRouterAutoScaleConfiguration to the route server object. Users should be able to create, update, and see the VirtualRouterAutoScaleConfiguration on the route server.

The following CLI cmdlets will need to be updated and tested with these changes:
az network routeserver create
az network routeserver update
az network routeserver show
az network routeserver list

3. Minimum API version required. What is the minimum API version of your service required to implement your feature?

2021-06-01

4. Swagger link. Provide a link to the location of your feature(s) in the REST API specs repo. If your feature(s) has corresponding commit or pull request in the REST API specs repo, provide them. This should be on the master branch of the REST API specs repo.

The virtualRouterAutoScaleConfiguration property is defined on the VirtualHubs object, to create a route server a user would then need to create an ipConfigurations object referencing the virtualHubs object. Both definitions are contained within the linked file below:

Examples of adding the autoscale config via powershell:
$autoscale = New-AzVirtualRouterAutoScaleConfiguration -MinCapacity 3
New-AzRouteServer -RouteServerName myRouteServer -ResourceGroupName myResourceGroup -Location eastus -HostedSubnet $subnetId -PublicIpAddress $publicIpAddress -VirtualRouterAutoScaleConfiguration $autoscale

$autoscale = New-AzVirtualRouterAutoScaleConfiguration -MinCapacity 3
Update-AzRouteServer -RouteServerName myRouteServer -ResourceGroupName ksteinmeyer-metricTesting1213 -VirtualRouterAutoScaleConfiguration $autoscale

9. Prerequisite to use this feature. Whitelisting subscription? Registering the feature for subscription? Is it available in public Azure?
