Description
Is your feature request related to a problem? Please describe.
Pandas has 4 options for the methods parameter in the corr() function: "pearson", "spearman", "kendall", and "callable" which accepts a callable object instead of a predetermined algorithm: https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.corr.html
CuDF currently only supports "pearson" and "spearman": https://docs.rapids.ai/api/cudf/stable/api_docs/api/cudf.DataFrame.corr.html
Describe the solution you'd like
Is it feasible to implement "callable" methods in cudf and dask+cudf?
Context
