[RFE] Allow hauler to pull content from authenticated registries

[zackbradys]

Is your feature request related to a problem? Please describe.

• Yes, see below

Describe the solution you'd like

• Add functionality to hauler so users are able to authenticate to authenticated/private registries (like the carbide registry) before using other commands such as hauler store sync or hauler store add or hauler store copy.
• Possible implementation could be hauler login and then we could remove the flags from hauler store copy.

Describe alternatives you've considered

• Using other tools to authenticate such as cosign login or docker login

Additional context

And to not confuse anyone looking at this, you can PULL from authenticated registries. You just have to run a docker/cosign login first. The idea behind the issue is having Hauler handle that for you just like it does for copying TO an authenticated registry.

For example, currently hauler store copy registry://<registry> takes credentials for authentication but hauler store add image and hauler store sync are missing that option. So running docker/cosign login prior to those commands are the workaround until we get this handled totally by Hauler.
