On Azure, would be nice to be able to use Workload Identity

Relevant information

Instead of using ClientSecretCredentialBuilder in AzureKeyVaultPersistence.kt , if you use DefaultAzureCredentialBuilder it would allow more fleximity on how to authorize airbyte to keyvault.

The Default Azure Credentital will wheck for environement variables for multiple way . This way we could use managed identity and be able to avoid using a client secret that will expire.

Same principle in storage account ( did not dig where it in the code ) .
