I ran the tests locally (py.test dask/dataframe) after adding product() and they all PASSED ✔️

Thanks for contributing. Looks good to me.

This does not "Close #1259", which has potentially several methods to implement - please remove this from the PR description.

Note that pd.DataFrame.product is pd.DataFrame.prod - I think you mentioned this in the connected issue.

Removed "Closes #1259" from the PR.

and yes, pd.DataFrame.product is pd.DataFrame.prod indeed! So, aliasing also worked!
Now, I ill pick up some other methods like axes or duplicated from #1259 and work on them

Thank you @martindurant for the quick review. This shall also help in my GSoC application. Now, I shall continue adding more methods #1259.
