[gpathak128]

Description

azure-identity-extensions: https://azuresdkdocs.blob.core.windows.net/$web/java/azure-identity-extensions/1.1.20/index.html

Add this as a dependency so that services like azure postgres flexible server maybe used with managed identity authentication rather than user/pass

Expected Use Cases

The ability to use

authenticationPluginClassName=com.azure.identity.extensions.jdbc.postgresql.AzurePostgresqlAuthenticationPlugin

in the jdbc url so that nessie can use a workload identity/managed identity to connect to the database server.
