BUG > Internal Load Balancer attempts to use regional cert

[kuwas]

Description

Current Behavior

• Attempting to use internal load balancer with an existing certificate will lead the controller to attempt to mount a "regional" certificate, but it cannot find the certificate since it is global.

      "kubernetes.io/ingress.class": "gce-internal"
      "ingress.gcp.kubernetes.io/pre-shared-cert": "default-sandbox"

googleapi: Error 404: The resource 'projects/<redacted>/regions/us-central1/sslCertificates/default-sandbox' was not found, notFound

Expected Behavior

• Internal load balancer should use certificate without issues

@kuwas The internal http load balancer actually only supports regional certificates: (docs) so this is expected behavior
