Working with adding an iceberg connector in Trino, we noticed that the properties file to configure the connector is required to be mounted in the worker pods too, not only in the coordinator pod as it is today. We need to add that mount in the worker Deployment object.

Adding a new connector configuration was hard because we specify each key to mount under /etc/trino/catalog. The pods should mount all keys in this path no matter what they are, to promote an easy way to add new data sources in Trino.
