Fixes #13 This builds on top of extensions catalog (see https://github.com/siderolabs/extensions/pull/225), and existing support for specifying extension in the flavor. Image Service resolve the list of extensions requested for a specific version of Talos into a list of container images, pulls them, and attaches them to the image request. Image Service also provides endpoints to get information about available Talos versions, supported extensions for each version, etc. I also refactored a bit flow around fetching & verifying image to re-use it in other flows, added support for authentication to the registry.
