OK, if this all passes I think it's ready. There are still a few warnings left, but those are more involved.
I added a toctree for the docstring guide. Here's the rendered version

This has come up a few times during the docstring improvements: we still had the `infer_dst` deprecations left over (deprecated in 0.15)

BUG: raise error when setting cached properties
State: closed

A bug I introduced myself some time ago in https://github.com/pandas-dev/pandas/pull/19991. Apparently the object needs to explicitly raise in the `__set__` method, otherwise the property is assumed to be settable:

```
In [6]: idx = pd.Index([1, 2, 3])

In [7]: idx.is_unique
Out[7]: True

In [8]: idx.is_unique = False

In [9]: idx.is_unique
Out[9]: False

In [10]: idx.is_monotonic
Out[10]: True

In [11]: idx.is_monotonic = False
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-11-b2a74ac7466c> in <module>()
----> 1 idx.is_monotonic = False

AttributeError: can't set attribute
```

`is_unique` is a cached property, didn't raise anymore on master (see above), in contrast to normal property `is_monotonic`.

This patch ensures also cached properties have the same error.
