Description

Adds a patch for Trino 481 that exposes HTTP proxy settings for the Iceberg REST catalog.

The Iceberg REST client ( HTTPClient ) already supports  rest.client.proxy.hostname ,  .port ,  .username  and  .password , but Trino's REST catalog had no way to set them. The patch adds these catalog properties and passes them through to the client properties:

•  iceberg.rest-catalog.http-proxy 
•  iceberg.rest-catalog.http-proxy.username 
•  iceberg.rest-catalog.http-proxy.password 

Nothing changes unless the new options are set.
