### Purpose
<!-- Linking this pull request to the issue -->
Linked issue: close #1727 #1559
Support $lake for Iceberg Tables via flink fluss
<!-- What is the purpose of the change -->
### Brief change log
Added pluggable lake format support enabling Iceberg alongside existing
Paimon integration. Core components now use reflection-based factory pattern
for format-agnostic catalog and table operations.
Flink Common Module:
- LakeCatalog.java: Refactored to accept DataLakeFormat enum; removed
hardcoded Paimon dependencies; added reflection-based catalog instantiation
- LakeTableFactory.java: Made pluggable via DataLakeFormat parameter; uses
reflection to create format-specific table factories
- FlinkCatalog.java: Added lake format detection from table.datalake.format
option; passes format to LakeCatalog
- FlinkTableFactory.java: Reads connector property to determine format;
passes context to LakeTableFactory
Dependencies:
fluss-flink-common/pom.xml
- Added iceberg-flink-${flink.major.version} (provided scope, non-shaded)
fluss-lake-iceberg/pom.xml
- Overridden Jackson BOM to 2.18.3 for Iceberg compatibility
-
- Added flink-connector-files and iceberg-flink dependencies (test scope)
Tests
### Tests
FlinkUnionReadLogTableITCase.java
- Added testReadIcebergLakeTableDirectly() for $lake suffix queries
### API and Format
<!-- Does this change affect API or storage format -->
### Documentation
<!-- Does this change introduce a new feature -->
Yes, need to add Iceberg read table directly support in the document.
