Allow remote logging config as multidoc for services

[rothgar]

Feature Request

Allow the remote logging configuration to be configured via a multidoc instead of needing a full machine bootstrap for services.

This would help debugging Talos earlier in the provisioning lifecycle (assuming network is available) for things like volume and network config.

Description

The current logging configuration for services requires a machine bootstrap which makes it difficult to get logs and troubleshoot issues before bootstrapping (e.g. in maintenance and installation phases).

Kernel logging does have an option to be provided as a separate document, but it doesn't appear service logging can be.

Similar to how the kernel logs are configured a MachineLogConfig would be adequate.

this is still needed and maybe a good idea to include as part of the networking multi-doc work.
