Add support of Azure Cosmos DB for MongoDB (vCore)

[oleksandr-bilyk]

Please add supports for new Azure Cosmos Db with MongoDB API .NET SDK https://learn.microsoft.com/en-us/azure/cosmos-db/mongodb/vcore/quickstart-dotnet

All teams that use AKS rely on Workload Identity. It should support Azure.Core.TokenCredential, DefaultAzureCredential and WorkloadIdentityCredential.

This SDK must work in multiple environments:

1. Localhost Mongo running in docker / docker-compose with basic user password auth.
2. Minikube hosted Mongo with basic user-password auth.
3. In future support Aspire
4. Azure Container App with Managed Identity Auth
5. AKS in public Azure with Workload Identity in federation with Managed Identity
6. Azure Local AKS disconnected from azure Workload Identity.

This auth must work with both basic auth and Azure.Core.TokenCredential handles all cases.

Localhost Mongo debugging environment docker-compose looks like this
