WorkloadIdentity/TokenCredential support is missing.

[dineshtsm]

In the Azure Cosmos client nuget we have support for Workload Identity. We create it and passed it to the method as TokenCredential. Similarly I dont see a constcutor for this Databricks client. Can you please add support for the same?

To give more context, pls have a look on line number 313 & 321 in the file : https://github.com/Azure/azure-cosmos-dotnet-v3/blob/dee9abaedf66b5663fdf33ea1f943cd9303e152a/Microsoft.Azure.Cosmos/src/CosmosClient.cs#L29
