What is not working as expected?

Legacy docker config:

{
  "auths": {
    "https://notationreg.azurecr.io/": {
      "auth": "",
      "email": ""
    }
  }
}

The registry address may contain the https or http prefix and may have a / at the end. Docker CLI still supports the configuration file, so Notation also needs to support it.

What did you expect to happen?

Notation should use the credentials in the docker config with legacy format.

How can we reproduce it?

create a docker config:

{
  "auths": {
    "https://notationreg.azurecr.io/": {
      "auth": "",
      "email": ""
    }
  }
}

docker pull/push works, but Notation list/sign/verify/inspect doesn't work.
