When we remove an auth of a registry from cluster global pull secret , if a pod using the image from that removed registry, The ppc is still able to inspect the image info.

We should:

• When the global pull secret is changed, the cache returns nit for previously cached images.
• The cache doesn't use the global pull secret when computing the hash and it's not cleared cache.go
• We'd either let the cache use the global pull secret when computing the hash or clear it when the global pull secret changes in facade.go
