Network Connectivity API Intergartion

[pre-yugandhar]

Google Cloud Support will be enabling the Network Connectivity API automatically to the projects where the Kubernetes Engine API is enabled.

The Network Connectivity API enables connectivity with and between Google Cloud resources. To build a foundation to help us improve the GKE cluster creation and auto scaling experience in the future.

And they recommend to ensure and updated any automation tools (e.g. Terraform) that create or manage Google Cloud projects and/or their APIs are configured to not disable the Network Connectivity API when using the Kubernetes Engine API. If the Network Connectivity API is disabled, it might cause issues related to IP management during GKE cluster creation or auto-scaling.

So,The Network Connectivity API integration need to update in the terraform resources files.
