DOC: expanded signatures for reindex, rename and reindex_axis
xref #15609 

I have expanded the signatures for _reindex_, _rename_, _reindex_axis_ in `series.py`, `frame.py` and `panel.py`

@PukkaPad you have included ``pandas/core/Users:MarianaSouza:Code:pro.textClipping``

somehow, can you remove

``git rm .......`` lgtm. you *may* have a flake issue (Travis CI will report if you do), you can check by doing

``git diff master | flake8 --diff``  Sorry!! Not in my house now, will do in a couple of hours!
