TST: make it possible to run tests without moto installed

description: pandas testing functions or related to the test suite

Comments:
a couple more
```
pandas/tests/io/conftest.py:import moto
pandas/tests/io/conftest.py:    moto.mock_s3().start()
pandas/tests/io/conftest.py:    moto.mock_s3().stop()
pandas/tests/io/json/test_compression.py:import moto

pandas/tests/io/test_excel.py:import moto
pandas/tests/io/test_excel.py:        with moto.mock_s3():
```
ah, yes, the difference is that this one is in a conftest, and so then even if you run some specific tests (not related to tests that use moto), it still tries to import it because it is in a conftest.py. 

But will fix the others as well.

BUG: Fix df.loc slice support
State: closed

- [x] tests added / passed
- [x] passes `git diff upstream/master -u -- "*.py" | flake8 --diff`

Labels:

Comments:
@jreback Oops, sorry! I overlooked another test.
The `MultiIndex` `loc` slicing work at the first level.
https://github.com/pandas-dev/pandas/blob/master/pandas/tests/test_multilevel.py#L1829
### Input:
```python
s = pd.Series(np.arange(8), pd.MultiIndex.from_product(([0, 1, 2, 3], list('ab'))))
s.loc[::2] = 200
s
```
### Output:
```
0  a    200
   b    200
1  a      2
   b      3
2  a    200
   b    200
3  a      6
   b      7
```

But, this returns the crazy result.
### Input:
```python
index = pd.MultiIndex(levels=[['foo', 'bar', 'baz', 'qux'], ['one', 'two','three']],
                      labels=[[0, 0, 0, 1, 1, 2, 2, 3, 3, 3], [0, 1, 2, 0, 1, 1, 2, 0, 1, 2]],
                      names=['first', 'second'])
frame = pd.DataFrame(np.random.randn(10, 3), index=index, columns=pd.Index(['A', 'B', 'C'], name='exp'))
frame.loc['foo':'bar':4]
```
### Output:
```
exp                  A         B         C
first second
foo   one     0.870785  1.900457 -0.907938
bar   two    -0.290714 -0.211697 -0.957994
```


@toobaz if you'd have a look
I think slicing by string is not good since `slice` seems not supporting to handle string.
@Licht-T : I'm confused. Unless I'm missing anything, your changes to code are limited to ``pd.MultiIndex.get_loc``, but in up-to-date master,
- none of the problematic examples in #8856 hits ``pd.MultiIndex.get_loc``
- none of the tests you add addresses any of the problematic examples in #8856 
- none of the tests you add hits ``pd.MultiIndex.get_loc``

... ?
closing as stale. ping if you want to update.
add benchmarks for timestamp parsing
State: closed

There's a reasonable case to be made that these and timeseries.ToDatetime benchmarks belong in the same place.  LMK if there's a preference.

Small flake8 fixups got timedelta.py passing, enabled linting for modules starting with "t".

@jreback @jorisvandenbossche the failure in https://travis-ci.org/pandas-dev/pandas/jobs/313729058 is our old friend, the clipboard failures, since https://github.com/pandas-dev/pandas/pull/17723 wasn't backported.

This should be good to go, and then I'll need to make sure I didn't miss any on this round. I'll merge later today.
hmm i though i has a commit where i moves the clipboard tests

but oh well
@TomAugspurger This can be merged? (the failure is a clipboard related, so I think can be ignored)
Oh, yes. I thought I had.

DEPR/CLN: Remove how keyword from df.rolling() etc.
State: closed

- [x] xref #18601 and #11603
- [x] passes `git diff upstream/master -u -- "*.py" | flake8 --diff`
- [x] whatsnew entry

The ``how`` parameter of df.rolling/expanding/ewm related methods was deprecated in 0.18 (#11603). This PR removes the parameter from the code base.

This PR is a continuation of #18601 (removed the ``freq`` parameter). Next up will be to remove ``pd.stats.*``).
