MAINT bump up CI dependencies

[ogrisel]

Apparently this hasn't been done in a while. Let's see if the CI is happy.

[ogrisel]

There are still 2 build failing because of a deprecation warning in pytest-xdist itself:

+ eval 'python -m pytest --showlocals --durations=20 --junitxml=test-data.xml --cov-config='\''/home/vsts/work/1/s/.coveragerc'\'' --cov sklearn --cov-report= -Werror::DeprecationWarning -Werror::FutureWarning -Werror::numpy.VisibleDeprecationWarning -Wignore:tostring:DeprecationWarning -Wignore:The\ distutils:DeprecationWarning -Wignore:distutils\ Version\ classes\ are\ deprecated:DeprecationWarning -Werror::pytest.PytestUnraisableExceptionWarning -n2 --pyargs sklearn'

however we do not use the --rsyncdir commandline option, so I am not sure what to do about this.

[ogrisel]

I will implement pytest-dev/pytest-xdist#825 (comment).

[ogrisel]

The filterwarnings directive is ignored. Maybe I need to quote it in one way or another?

[glemaitre]

Maybe we can just pin pytest to have it working and await to be fixed upstream.
We can upgrade the other dependencies.

[ogrisel]

I will pin pytest-xdist.

[ogrisel]

Hum I don't understand how test_fit_gibbs could work it seems like a very brittle test... Maybe I am missing something.

[glemaitre]

We will comeback on it when dealing with the global_seed.

[ogrisel]

I forgot to re-trigger [scipy-dev] in the last commit push. Let me wait for the current build to complete before re-pushing with the extra builds.

[jjerphan]

LGTM once the CI runs are green.

[ogrisel]

Yeah, it's green, even for pypy!
