Summary

Removes the namespace from the ClusterSecretStore, since this Kind is not namespace aware.

Prior to this fix, the secretRef for the ClusterSecretStore and the final secret were required to be in the same namespace in order for ESO to work.

We move the namespace to be applied to the key references, so we can store the keys in a different namespace than the external-secret itself.
