Fix the ServiceAddress update in Transport server and Virtual Server

[pmaddev]

Environment

• Application Services Version: 3.52.0
• BIG-IP Version: 17.1

Summary

The customer encountered a problem when a TransportServer object without serviceAddress parameter initially. And was updated with new serviceAddress parameter being customized. As a result, the BIG-IP systems would fail to process the declaration.

Steps To Reproduce

When the customer first applied the TransportServer object, there was no 'serviceAddress' parameter.

1. Configure as per the below config for reference
apiVersion: [cis.f5.com/v1](https://cis.f5.com/v1)
kind: TransportServer
metadata:
annotations:
labels:
f5cr: "true"
name: ts-nginx-test1
namespace: kube-system
spec:
bigipRouteDomain: 0
ipamLabel: Default
mode: standard
pool:
monitor:
interval: 20
timeout: 10
type: tcp
service: nginx-test1
serviceNamespace: default
servicePort: 80
snat: auto
type: tcp
virtualServerPort: 8081

2. Observe the following error response:

When the customer attmepted to update the TransportServer object, they included the 'serviceAddress' parameter to allow route advertisement.
apiVersion: [cis.f5.com/v1](https://cis.f5.com/v1)
kind: TransportServer
