[Feature]: Multiple ollama instances on single host support

Area

Routing and scheduling

User problem

I have a system with two GPUs from different vendors, one being a nvidia GPU. I've had to setup two ollama instances locally on different ports to get this to work with different settings. I'd like to be able to expose both ollama instances to the cluster

Desired outcome

Both ollama instances show up for a node (or it appears as two nodes)

Alternatives considered

No response

Compatibility and security implications

No response

Validation approach

Launch two ollama instances on different ports, ideally with specific GPUs enabled for each

Comienza por los puntos de entrada de routing y scheduling que descubren y exponen las instancias de Ollama. Traza cómo se representan el endpoint de Ollama y la configuración de un nodo, y determina después si dos instancias deben exponerse como nodos separados o como endpoints en un solo nodo. Valídalo iniciando dos instancias de Ollama en puertos diferentes con configuraciones de GPU separadas y confirmando que ambas aparecen en el clúster.
