Similar to the work done for AWS STS and Azure WIF support, the console UI (specifically OperatorHub) needs to:

1. warn users when they are on an GCP cluster that support GCP's Workload Identity Management and the operator they will be installing supports it
2. Subscribing to an operator that supports it can be customized in the UI by adding fields to the subscription config field that need to be provided to the operator at install time.

CONSOLE-3776 was adding filtering for the GCP WIP case, for the operator-hub tile view. Part fo the change was also check for the annotation which indicates that the operator supports GCP's WIF:

features.operators.openshift.io/token-auth-gcp: "true"

AC:

• Add warning alert to the operator-hub-item-details component, if the cluster is GCP with WIF, similar to Azure and AWS.
• Add warning alert to the operator-hub-subscribe component, if the cluster is GCP with WIF, similar to Azure and AWS.
• If the cluster is in GCP WIF mode and the operator claims support for it the the subscription page provides configuring 4 additional fields, which will be set on the Subscription's spec.config.env field:

• • POOL_ID
  • PROVIDER_ID
  • SERVICE_ACCOUNT_EMAIL
• Default subscription to manual for installs on WIF mode clusters for operators that support it.
