It would be very useful to have the ability to assign multiple domains to a single resource in Pangolin.

Currently, a resource seems to be tied to a single domain.
This limits flexibility when a service should be accessible via multiple domains or subdomains.

Proposed Feature

Add support for specifying multiple domains for a given resource, along with a setting to determine how Pangolin should handle requests to these domains.

Two modes could be available:

Primary Domain Redirect Mode
- One domain is marked as the primary.
- All requests to any other assigned domain are redirected to the primary domain via HTTP 301 (permanent redirect).
- Ensures canonical URLs and SEO consistency.
Multi-Domain Mode
- All assigned domains serve the same resource directly.
- No redirects are performed; each domain remains independently accessible.

Benefits

SEO control: Primary domain redirection prevents duplicate content issues.
Brand flexibility: Serve content under multiple brand domains without creating duplicate configurations.
Simplified configuration: Manage all domains for a resource in one place rather than duplicating resources.
Subdomain preference: Especially useful for cases like example.ch and www.example.ch, allowing one of them to be declared as the primary domain while redirecting the other.
