Removing cache and image translation from Hub&Spoke

Until now we used a cache in order not to call to the registry every mcm reconciliation.

The bug is when we create, delete and then create again
mcm with the same image tag but different digest.

Now that we leverage Crio to pull images and that ICSPs are deprecated in favor to IDMS and ITMS,
we can remove the caching mechanism.
