Support Azure OpenAI

[asimpson]

Relevant docs

High-level tasks:

• reach out to Azure to get access for testing and development
• make URL field configurable since the URL changes based on the deployment of the model in Azure. We'll need two pieces:
  • Deployment name
  • Endpoint, e.g. https://docs-test-001.openai.azure.com/

Current OpenAI support only allows OpenAI key. Please expand that to use Azure's OpenAI instances and API keys

@asimpson If you're ready to switch over to grafana-llm-app support for all your LLM API needs ✨ , Azure support is now stable over there -- tbh, partly driven by knowing you wanted the option. Plus it turned out to be pretty straightforward.

Let us know when when you're picking that up (happy to help), or if there are any blockers / concerns.

Incident Auto-summary migrated over by keeping dual support for now -- if grafana-llm-app is configured, use it, otherwise check for local LLM config -- and will drop the local config path in a future iteration.
