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.
