Code Sample, a copy-pastable example if possible

In [2]: pd.Series(-1, index=range(3)).rename({}, axis=0)
TypeError                                 Traceback (most recent call last)
<ipython-input-2-2588ce9f0737> in <module>()
----> 1 pd.Series(-1, index=range(3)).rename({}, axis=0)

/home/pietro/nobackup/repo/pandas/pandas/core/ in rename(self, index, **kwargs)
   2648         if non_mapping:
   2649             return self._set_name(index, inplace=kwargs.get('inplace'))
-> 2650         return super(Series, self).rename(index=index, **kwargs)
   2652     @Appender(generic._shared_docs['reindex'] % _shared_doc_kwargs)

/home/pietro/nobackup/repo/pandas/pandas/core/ in rename(self, *args, **kwargs)
    850         if kwargs:
    851             raise TypeError('rename() got an unexpected keyword '
--> 852                             'argument "{0}"'.format(list(kwargs.keys())[0]))
    854         if com._count_not_none(*axes.values()) == 0:

TypeError: rename() got an unexpected keyword argument "axis"

Problem description

Sure, it is redundant, but for compatibility it would be good to support it.

In particular, I have an old method which calls obj.rename_index(axis=n) with obj sometimes being a DataFrame and sometimes a Series, and now I get a warning asking me to use rename... but if I do, I get the above error.

Expected Output

The same as without axis=0.

Output of pd.show_versions()
