#### Description
#50238
This PR mainly adapts Iceberg tables to the new Metastore (MS) parameters
and represents an architectural refactoring rather than introducing new
features. The key changes include:↳
Adaptation to New Storage Parameter Passing Mechanism Since Iceberg’s FileIO
implementation is not yet complete, storage configurations are temporarily
passed via parameters. Iceberg internally uses the HDFS protocol, so a
temporary interface has been added in the storage layer to convert parameters
to HDFS-compatible configurations. This interface is a temporary solution and
will be removed once Iceberg’s FileIO is fully implemented.
Compatibility with Multiple Iceberg Metastores
Unified parameter adaptation has been implemented to support various Iceberg
Metastores such as S3 Table, HMS, Hadoop Glue, etc., ensuring consistent and
compatible parameter handling across different Metastore types.
Unified Backend Parameter Transmission
The logic for passing storage parameters to the BE (Backend) has been
streamlined by removing previous multiple conversion steps and adopting a
unified new storage parameter format, improving architectural clarity and
maintainability.
#### Background
Currently, the parameter handling for Iceberg table Metastore storage
configurations is complex and FileIO support is incomplete. This refactoring
improves architectural consistency by adapting to new parameter passing and
transmission mechanisms. Further simplifications will be made after Iceberg
FileIO support is finalized.
