Connect to multiple Azure accounts

Feature Request / Improvement

I got PyIceberg working connecting to a SQL catalog (Postgres JDBC) and connecting to an ADLFS account using the account-name and account-key configuration settings.

However our Iceberg catalog points to tables residing in many different storage accounts.

It would be good if we could configure multiple connections to adlfs accounts and have the Catalog class detect which key to use.
