feat: Support private repository when using kairos-agent bundle-install

[Bao0ne]

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

When I tried to use bundle to publish software, I found that it had no way to pull images from the private repository.

Describe the solution you'd like

Hope it will be supported when kairos-agent install-bundle：

• Provide private repository authentication
• Read repository information from the specified configuration file like luet install --config

Additional context

Currently, authentication information cannot be added when luet repo add, I try to make it support：mudler/luet#370

In kairos-sdk：https://github.com/kairos-io/kairos-sdk/blob/d334d86d4369929e47d569d9d8a6eeb4698e55ca/bundles/bundles.go#L287

Is it expected to point the software installation location(--system-target) and repo config to the same location? I think most of the time software needs a separate directory for storage.

In kairos-sdk：https://github.com/kairos-io/kairos-sdk/blob/d334d86d4369929e47d569d9d8a6eeb4698e55ca/bundles/bundles.go#L304
