:sparkles: Seeding from resources at URL.

[jortel]

Redesign to see the hub from a URL referencing a directory of YAML files.
This can be git repository that builds an image to be used as an init container by the hub.
This includes:

• Tag
• TagCategory
• Users
• Roles/scopes.
• RuleBundles (which includes a bundle for builtin rules.)

As part of this, the RuleSet.Metadata needs to be replaced with RuleSet.Labels and Metadata removed from the model.
