I am adding correlation and covariation operations for mapd backend.

I think it would be good be the on the ibis core.

I am using pandas name for this operations:

https://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.cov.html
https://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.corr.html

Does it make sense?
