BUG: Series.rename raises error on values accepted by Series constructor.
#### Sample

```python
import pandas as pd

class MyIndexer:
    pass

i1 = MyIndexer()
s = pd.Series([1, 2, 3], name=i1) # allowed
s.rename(i1) # raises error
```

The error stack trace is the following:

```python
Traceback (most recent call last):
  File "test.py", line 8, in <module>
    s.rename(i1) # raises error
  File "/usr/local/lib/python3.6/dist-packages/pandas/core/series.py", line 3736, in rename
    return super(Series, self).rename(index=index, **kwargs)
  File "/usr/local/lib/python3.6/dist-packages/pandas/core/generic.py", line 1091, in rename
    level=level)
  File "/usr/local/lib/python3.6/dist-packages/pandas/core/internals/managers.py", line 171, in rename_axis
    obj.set_axis(axis, _transform_index(self.axes[axis], mapper, level))
  File "/usr/local/lib/python3.6/dist-packages/pandas/core/internals/managers.py", line 2004, in _transform_index
    items = [func(x) for x in index]
  File "/usr/local/lib/python3.6/dist-packages/pandas/core/internals/managers.py", line 2004, in <listcomp>
    items = [func(x) for x in index]
TypeError: 'MyIndexer' object is not callable
```

#### Description

Series.rename handle anything that isn't a scalar or list-like as a mapping. 

#### Proposed change

Change the following code (from Series.rename):
```python
non_mapping = is_scalar(index) or (is_list_like(index) and not is_dict_like(index))
if non_mapping:
    return self._set_name(index, inplace=kwargs.get("inplace"))
return super().rename(index=index, **kwargs)
```
to
```python
if callable(index) or is_dict_like(index):
    return super().rename(index=index, **kwargs)
else:
    return self._set_name(index, inplace=kwargs.get("inplace"))
````

so anything that isn't a dict or a callable will be treated the same way as a scalar or list-like.
