BUG: pass *args and **kwargs for wrapped methods in Groupby (#14107)

[yonatanp]

• closes pandas.core.groupby.SeriesGroupBy.hist doesn't propagate **kwargs #14107
• tests added / passed
• passes git diff upstream/master | flake8 --diff
• whatsnew entry

Methods such as 'hist' that take keyword arguments would now be able to be called via a Groupby object and the keyword args would be passed onwards to matplotlib as the user expects.

tests!

pls add tests

[yonatanp]

BTW, I just removed a duplicate dictionary entry on test_tslib.py.
It was there for a year now and I have no idea how anything was able to pass lint until now.

[yonatanp]

I'll need some help at this point (@jreback or others available). My change was a simple one-liner, and I added a test that fails without my change and succeeds with it; so I'm pretty certain my change is fully covered.
However codecov/patch says 0.00%. I'm not sure what it means and how to fix it. Help?

[yonatanp]

Pinging again. I'd really love to contribute this tiny piece, but if it is just remaining as clutter, I'll remove the PR to avoid future confusion.

I think your example fails in current master. can you clarify?

[jreback]

@yonatanp I am still unclear what the exact issue is here, can you show an example?

[jreback]

can you rebase
