[jira] [Created] (ARROW-13835) [Python] Add utility to merge schemas

Alessandro Molina created ARROW-13835:
-----------------------------------------

             Summary: [Python] Add utility to merge schemas
                 Key: ARROW-13835
                 URL: https://issues.apache.org/jira/browse/ARROW-13835
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Python
    Affects Versions: 5.0.0
            Reporter: Alessandro Molina


In R we have the `unify_schemas` utility which allows to merge two or more schemas, in Python such feature would be helpful but we don't seem to provide it. 

Such feature already exists in C++  ( https://github.com/apache/arrow/blob/27affa3181708c4f800f9d0a70603fb3390d6462/cpp/src/arrow/type.cc#L1722-L1744 ) and should be exposed in PyArrow and documented under https://arrow.apache.org/docs/python/api/datatypes.html
