Allow to set registry mirrors

[no-12]

Let's assume a scenario there network bandwidth is limited. And that there a local mirrors of public/private OCI regitries available.

It would be nice to be able to configure a list of registry mirrors for things like:

• HookOS to use locally mirrored images for tink-agent and actions
• oci2disc to use locally mirrored images

Using mirrors is much more convenient than using the edited image name of a locally published image. This makes it also possible to auto fallback to the original image registry when no mirrors are available.

I'm new to tinkerbell and also to go, but willing to contribute such features. So my question is, if that's even possibe with the current architecture of tinkerbell?

Hey @no-12 , thanks for opening this issue. I think this is better suited for the https://github.com/tinkerbell/hook repo as that is where container runtime configuration options are set.

I will move this issue over there.
