Update coveralls to 1.11.0

[pyup-bot]

This PR updates coveralls from 1.10.0 to 1.11.0.

Changelog

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!).
