[Feature] Tag delete flag not to fail if tag already deleted #928
Description
In scripts you may delete many tags (e.g. per-arch tags like foo-bar-aarch64), and in case of network errors you may have retries.
So part of tags may be already deleted.
Current Behavior
regctl tag delete registry/image:foo-bar-aarch64
failed to request manifest head registry/image:foo-bar-aarch64: request failed: not found [http 404]:
echo $? # != 0
Expected Behavior
Add flag like --missing-ok, so:
regctl tag delete --missing-ok registry/image:foo-bar-aarch64
warning: failed to request manifest head registry/image:foo-bar-aarch64: 404
echo $? # == 0
