    [python] Add requests as dependency (#7960)
    
    ### Purpose
    
    Currently requests is required to using Paimon, otherwise it will raise
    error when importing `paimon` on current main branch:
    
    ```
    >>> import pypaimon
    Traceback (most recent call last):
      File "<python-input-0>", line 1, in <module>
        import pypaimon
      File "/home/asaka/paimon/paimon-python/pypaimon/__init__.py", line 26, in 
<module>
        from pypaimon.catalog.catalog_factory import CatalogFactory
      File 
"/home/asaka/paimon/paimon-python/pypaimon/catalog/catalog_factory.py", line 
23, in <module>
        from pypaimon.catalog.filesystem_catalog import FileSystemCatalog
      File 
"/home/asaka/paimon/paimon-python/pypaimon/catalog/filesystem_catalog.py", line 
45, in <module>
        from pypaimon.table.file_store_table import FileStoreTable
      File 
"/home/asaka/paimon/paimon-python/pypaimon/table/file_store_table.py", line 25, 
in <module>
        from pypaimon.read.read_builder import ReadBuilder
      File "/home/asaka/paimon/paimon-python/pypaimon/read/read_builder.py", 
line 20, in <module>
        from pypaimon.common.predicate import Predicate
      File "/home/asaka/paimon/paimon-python/pypaimon/common/predicate.py", 
line 29, in <module>
        from pypaimon.manifest.schema.simple_stats import SimpleStats
      File 
"/home/asaka/paimon/paimon-python/pypaimon/manifest/schema/simple_stats.py", 
line 22, in <module>
        from pypaimon.table.row.generic_row import GenericRow
      File 
"/home/asaka/paimon/paimon-python/pypaimon/table/row/generic_row.py", line 28, 
in <module>
        from pypaimon.table.row.blob import BlobData
      File "/home/asaka/paimon/paimon-python/pypaimon/table/row/blob.py", line 
24, in <module>
        from pypaimon.common.uri_reader import UriReader, FileUriReader
      File "/home/asaka/paimon/paimon-python/pypaimon/common/uri_reader.py", 
line 23, in <module>
        import requests
    ModuleNotFoundError: No module named 'requests'
    ```
    
    With the latest release of `pypaimon` on PyPI, we can import `pypaimon`,
    but `import CatalogFactory from pypaimon` will raise the same error.
    
    Adding `requests` to `requirements.txt` can resolve this error.
    `requests 2.21.0` was released in 2018, I think it's old enough to be
    used as the minimum version range.
    
    ### Tests
    
    (cherry picked from commit dd79ff78c51b9c040196f7841d4837d2e2ed87f7)
