[Discussion] Support for Multiple API Connections per AiProvider

Problem/Motivation

For some providers, it can be especially useful to use multiple connections. We have an example from ✨ Add support (provider) for Azure Openai (Europe / GDPR loves that) Active where, in Azure OpenAI, we have different models deployed to different Azure regions. This means that the API URL and even the API keys are different.

Steps to reproduce

Imagine that you need to use two different API keys from one provider for different AI operations.

Proposed resolution

It is possible to implement a provider-specific solution, but perhaps we can find a more generic solution that will allow any provider to use multiple connections.

Remaining tasks

User interface changes

API changes

Data model changes
