[feature] Save installation media configurations

[fracek]

Problem Description

At the moment my cluster is using 2 to 4 different machine configurations with non-default values:

• Change talos version to the latest available
• Change options to my cloud provider
• Add custom extensions, with different options for amd and intel machines
• Add custom labels (targeting machine classes labels)

Reconfiguring the image every time I deploy a new machine to the cluster is error prone because it's easy to forget something important like a custom extension.

Solution

It would be nice to have an option to "save" an installation media configuration so that it can be quickly retrieved at a later time. Ideally, it would also have an option to quickly bump the talos version to the latest stable release.

Alternative Solutions

At the moment, I simply store the PXE boot url in a Notion document.
