Support pull from habor registry in proxy mode an push to harbor

[ptempier]

Not sure why its not working, maybe i do something bad.
From other ticket i understand it supposed to work with OCI registry.

What i tried :

ollama pull habor-server//ollama.com/library/llama3:text
Error: pull model manifest: 400

ollama pull habor-server/ollama.com/llama3:text
Error: pull model manifest: 400

ollama cp llama2:7b habor-server/aistuff/llama2:7b
ollama push habor-server/aistuff/llama2:7b
retrieving manifest
Error: Get "harbor?nonce=zzzz&scope=&service=&ts=xxxx": unsupported protocol scheme ""
