[Python] pyarrow.serialize does not support dask dataframe

Currently pyarrow knows how to serialize pandas dataframes but not dask dataframes.

SerializationCallbackError: pyarrow does not know how to serialize objects of type <class 'dask.dataframe.core.DataFrame'>. 

Pickling the dask dataframe foregoes the benefits of using pyarrow for the sub dataframes.

Pyarrow support for serializing dask dataframes would allow storing dataframes efficiently in a database instead of a file system (e.g. parquet).
