### Feature Request / Improvement
Playing around with `pyflink` and noticed that the Hadoop dependency is
required when using the REST catalog:
```python
➜ ~ python3.9

[Clang 14.0.0 (clang-1400.0.29.202)] on darwin

>>> import os
>>>
>>> from pyflink.datastream import StreamExecutionEnvironment
>>>
>>> env = StreamExecutionEnvironment.get_execution_environment()
>>> iceberg_flink_runtime_jar =
"/Users/fokkodriesprong/Desktop/iceberg/flink/v1.17/flink-runtime/build/libs/iceberg-flink-runtime-1.17-1.3.0-SNAPSHOT.jar"
>>>
>>> env.add_jars("file://{}".format(iceberg_flink_runtime_jar))
>>>
>>> from pyflink.table import StreamTableEnvironment
>>>
>>> table_env = StreamTableEnvironment.create(env)
>>>
>>> table_env.execute_sql("""

When using a Hadoop or Hive catalog, this makes perfect sense but would be
nice to make it optional when using the REST catalog.
