Should save the release signature in the archive tar file instead of count on the enterprise cache (or working-dir)

1) Prepare data for enterprise registry use mirror2disk+disk2mirror mode with the following command :
kind: ImageSetConfiguration
apiVersion: mirror.openshift.io/v2alpha1
mirror:
  platform:
    graph: true
    channels:
    - name: stable-4.15

`oc-mirror -c config-38037.yaml  file://out38037 --v2`
`oc-mirror -c config-38037.yaml --from file://out38037  docker://my-route-zhouy.apps.yinzhou-88.qe.devcluster.openshift.com --v2  --dest-tls-verify=false`

  2) Prepare the env to simulate the enclave cluster :
cat /etc/squid/squid.conf
http_port 3128
coredump_dir /var/spool/squid
acl whitelist dstdomain "/etc/squid/whitelist"
http_access allow whitelist
http_access deny !whitelist

cat /etc/squid/whitelist 
my-route-zhouy.apps.yinzhou-88.qe.devcluster.openshift.com             -------------registry route  (oc get route -n your registry app's project)
update-service-oc-mirror-route-openshift-update-service.apps.yinzhou-88.qe.devcluster.openshift.com        ---osus route  (oc get route -n openshift-update-service)

Sudo systemctl restart squid
export https_proxy=http://127.0.0.1:3128
export http_proxy=http://127.0.0.1:3128

Setting registry redirect with : 
cat ~/.config/containers/registries.conf 
[[registry]]
  location = "quay.io"
  insecure = false
  blocked = false
  mirror-by-digest-only = false
  prefix = ""
  [[registry.mirror]]
    location = "my-route-zhouy.apps.yinzhou-88.qe.devcluster.openshift.com"
    insecure = false


3) Simulate enclave mirror with same imagesetconfig with command :
 `oc-mirror -c config-38037.yaml file://new-folder --v2`

3) The mirror2disk failed with error :   

No error and should contain the signature in the archives tar file , not count on the enterprise cache (From  custom usage, they may on different machine for enclave cluster , or they may not use the same directory )
