Add Iceberg REST catalog support to TrinoCatalog #849

Part of https://github.com/stackabletech/internal-issues/issues/156

Currently we only offer Hive metastore, we also want to offer an Iceberg REST catalog.

A working example can be found here

• Decision: feat: Support configuring Iceberg REST catalog #950
• Implementation: feat: Support configuring Iceberg REST catalog #950 and chore: Default REST catalog tls to null #972
• Update nifi-operator iceberg test to use this mechanism: test: Use SDP support to configure Iceberg REST catalog in TrinoCatalog nifi-operator#1022
• [ ]~ Go though all stackabletech repos and bump the TrinoCatalog to v1alpha2~ I'm actually thinking of skipping this, as existing customers will likely continue on v1alpha1 and this way we increase the test coverage
