Consistent Return Structure for Rolling Apply
State: closed

- [X] closes #14013
- [X] tests added / passed
- [X] passes `git diff upstream/master -u -- "*.py" | flake8 --diff`
- [x] whatsnew entry

With the changes made in #20949 it appears possible to fix this bug by suppressing a `catch` block that was internal to Rolling's `_apply`. I'm not sure what the purpose of this catch as it essentially allows values to bypass the applied function...Only one test broke on removal which looked wrong anyway, so I updated it as such

Thanks @jreback, fixed!
lgtm. ping on green. I pushed some cleaning of the test.
thanks @Licht-T

Since this is performance related - is there an ASV for this? If not can you add and post result?
Different solution needed; removing coercion causes type errors with reduce operations.
@fivemok could you post more details about the issues? Future contributors trying to fix this would appreciate it.
@TomAugspurger apologies for the lack of details. The `from_codes` function can take arrays of non-numeric types which is coerced to an array of `np.int64`. Removing coercion completely can break NumPy reduction operations like `np.max` due to array having a flexible type. I think only removing coercion for arrays of numeric dtype will work. I'll create a new PR after running the tests.

@WillAyd should the full ASV be posted or just for `pd.Categoricals`?
@fivemok just for `pd.Categoricals` and the relevant method(s)
@WillAyd @TomAugspurger I created a new PR [here](https://github.com/pandas-dev/pandas/pull/21000) for this issue.

Simplified this a bit with the Index constructor; however, I wanted to avoid turing all bins into an Index type unless this is an API change we want to make. 

Also, I created #20964 since the Index constructor does not correctly localize values with a datetimetz dtype specified. 
Updated and ready for a final review @jreback
Add pip 9.0.3 to conda environment to avoid numpy 1.9.3 error

no this is not a solution
Answered on the issue @miguelmorin.
Yes, and I just read the contributing guidelines and realized that my PR failed the tests. Sorry about that.
