- Move from the deprecated standard-test-scripts to the better
supported standard-test-basic. This can install test dependencies.
- Drop the obsolete standard-test-overlay, it does not even exist any
more.
- Drop test-canary. This was being used to test the CI gating, but this
has been done now.
Later once the upstream no longer uses phantomjs, we should
be able to execute the entire integration test suite.
This includes the standard-test-overlay role, and the
standard-test-scripts role. These will be suggested to the
standard-test-roles repo.
