.NET Aspire + Azure OpenAI demo app

Currently a WIP, best to ask me for how to run it locally, but here's the general idea:

Create an Azure OpenAI resource with a gpt-35-turbo model and a text-embedding-ada-002 model
Create an Azure AI Speech resource (optional - disable by setting Speech:Enabled to false in appsettings.json)
Create an appsettings.Development.json file in the AppHost project and populate the details from Azure Resources as per the empty ones in the appsettings.json
Launch the app, navigate to the frontend -> management screen
Wait for podcasts to load, choose the one(s) to index and click the Index Selected Items button
Wait for a bunch of time (no UI progress, but you can click the "Retrieve Status" button to see the indexing status)
Once indexing is done, go to the frontend / index, enter a prompt and see what happens
