Connecting to GCP

There are 3 options when connecting to GCP:

1. GKE workload identity (the default if no connection or credentials is specified)
2. connection, this is the recommended method, connections are reusable and secure

metadata:
  name: database-backup-example
spec:
  schedule: "@every 5m"
  databaseBackup:
    - name: backup
      maxAge: 6h
      gcp:
        project: google-project-name
        instance: cloudsql-instance-name
        gcpConnection:
          connection: connection://gcp/internal

3. accessKey and secretKey EnvVar with the credentials stored in a secret.
