Update coveralls to 2.0.0

[pyup-bot]

This PR updates coveralls from 1.6.0 to 2.0.0.

Changelog

2.0.0

Compatiblity (BREAKING CHANGES)

*  We have now dropped support for End-Of-Life'd versions of Python and
particularly old versions of the `coverage` library; if you are still using
Python v2.7 or v3.4, or you are using `coverage<4.1`, this library will no
longer be compatible starting from this release -- please pin to
`coveralls<2.0.0`.

<a name="1.11.1"></a>

1.11.1

Bug Fixes

* **github:**  rename to github-actions ([9e65a059](9e65a059))
 This fixes a regression introduced with v1.11.0, which may have prevented
 usage of this library on Github Actions.

<a name="1.11.0"></a>

1.11.0

Fixes

* **github:**  add `service_number` for github actions ([9f93bd8e](9f93bd8e))
 This should fix support for parallel builds.

Compatibility

*  Python 2.7 and 3.4 are now officially End-Of-Life'd. Consider them deprecated
from the perspective of this package -- we'll remove them in an upcoming
release (likely the first one which requires non-trivial work to continue
supporting them!).

<a name="1.10.0"></a>

1.10.0

Features

*  support coverage>=5.0 (214) ([4a917402](4a917402))

<a name="1.9.2"></a>

1.9.2

Bug Fixes

* **github:**  fixup incorrect API usage (209) ([c338cab4](c338cab4))

<a name="1.9.1"></a>

1.9.1

Compatibility

*  this release marks Python 3.8 as officially supported. Earlier versions probably
supported Python 3.8 too, but now we're *sure*.

<a name="1.9.0"></a>

1.9.0

Features

* **support:**  support Github Actions CI (207) ([817119c3](817119c3))

Bug Fixes

* **compatibility:**  fixup coverage.__version__ comparisons (208) ([03a57a9a](03a57a9a))

<a name="1.8.2"></a>

1.8.2

Internal

* **dependencies**: update pass urllib3<1.25 pin, now that that's fixed.

<a name="1.8.1"></a>

1.8.1

Bug Fixes

* **dependencies:**  pin `coverage` to `< 5.0`, since the current `5.0` alphas are
                  introducing breaking changes. Once `5.0` is stable, we'll
                  remove the pin.

<a name="1.8.0"></a>

1.8.0

Features

* **flag:**  allow disabling SSL verification ([2e3b5c61](2e3b5c61))

Bug Fixes

* **git:**  fix support for case where git binary is missing ([5bbceaae](5bbceaae))

<a name="1.7.0"></a>

1.7.0

Features

* **api:**  support pull requests on buildkite (197) ([2700e3e2](2700e3e2))

Bug Fixes

* **cli:**  ensure upload failures trigger cli failures ([16192b84](16192b84))
