New description:

 #3267 pinned some dependencies including coverage, because integration
 tests were failing on CI.  It isn't clear if coverage still needs to
 remain pinned at ~= 4.5.

 Let us unpin coverage and see what happens in CI!

 For more context, the follow-up ticket to this would be #3385, which will
 attempt to use [[https://coveralls.io|coveralls.io]] for code coverage
 checks.  We are not entirely satisfied with
 [[https://codecov.io|codecov.io]], which we currently use.  For example,
 it is not always clear why codecov checks turn disapprove of certain PRs,
 even when test coverage remains unchanged.

 Now, in order to upload coverage reports to codecov.io, we will need to
 use [[https://github.com/coveralls-clients/coveralls-python|coveralls-
 python]], which requires that coverage reports should be in coverage 5.0
 format.  Which is the real motivation for unpinning coverage.

 (See coverage
 [[https://coverage.readthedocs.io/en/coverage-5.2.1/changes.html#version-5-0a2-2018-09-03|changelog]]:
 "Coverage’s data storage has changed. In version 4.x, .coverage files were
 basically JSON. Now, they are SQLite databases.")
