📄 Description

Resolves https://github.com/ollama/ollama/issues/3144

This pull request is to add /metrics endpoint and generally used metrics.
It exposes default prometheus metrics and custom metrics for request endpoints.

This PR does not try to cover all metrics to keep it simple. If this looks good. I could add few more that will be useful.

How to test:
once Ollama server is running pull a model and list(or any other Ollama actions)

curl http://127.0.0.1:11434/metrics

example custom metrics(not all are shown since i tried only few commands):

curl http://127.0.0.1:11434/metrics | grep -i ollama
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

# HELP ollama_model_requests_total The total number of requests on all endpoints.
