Provide feature to allow customer to create routing rule for Direct Link 2.0

I have created new Direct Link 2.0 service to setup a interconnection between a IBM Cloud VPC and a IBM Power Subnet.

I have found out the routing won't automatically work after I created the connection. I will need to create support ticket, then support will setup the routing between the VPC and the Power subnet.

I suggest to add features :

1. Since the VPC and Power subnet is already defined in the DL 2.0 connection, the routing should be automatically created.

2. Additionally Customer should be provided with option to add larger subnet routing rules for the connection.

For example, if I have a VPC with address prefix 10.100.0.0/24 and a Power subnet 10.100.1.0/24, once I created the DL connection, the routing between them should be automatically created. I should also have option to tell Power subnet to route 10.0.0.0/8 , a bigger subnet through the VPC. That way we can setup VSI ( or IBM VPN server when it's capable ) as transit VPN gateway to allow full connectivity between Power subnet and On-premises network.
