[pyup-bot]

This PR updates pytest-cov from 2.10.1 to 2.11.0.

Changelog

2.11.0

-------------------

* Bumped minimum coverage requirement to 5.2.1. This prevents reporting issues.
Contributed by Mateus Berardo de Souza Terra in `433 <https://github.com/pytest-dev/pytest-cov/pull/433>`_.
* Improved sample projects (from the `examples <https://github.com/pytest-dev/pytest-cov/tree/master/examples>`_
directory) to support running `tox -e pyXY`. Now the example configures a suffixed coverage data file,
and that makes the cleanup environment unnecessary.
Contributed by Ganden Schaffner in `435 <https://github.com/pytest-dev/pytest-cov/pull/435>`_.
* Removed the empty `console_scripts` entrypoint that confused some Gentoo build script.
I didn't ask why it was so broken cause I didn't want to ruin my day.
Contributed by Michał Górny in `434 <https://github.com/pytest-dev/pytest-cov/pull/434>`_.
* Fixed the missing `coverage context <https://coverage.readthedocs.io/en/stable/contexts.html>`_
when using subprocesses.
Contributed by Bernát Gábor in `443 <https://github.com/pytest-dev/pytest-cov/pull/443>`_.
* Updated the config section in the docs.
Contributed by Pamela McA'Nulty in `429 <https://github.com/pytest-dev/pytest-cov/pull/429>`_.
* Migrated CI to travis-ci.com (from .org).
