Add note to existing QA issue when environment changes
Takes advantage of changes to deploy-tooling in https://ops.gitlab.net/gitlab-com/gl-infra/deploy-tooling/merge_requests/144
This is a boring solution to https://gitlab.com/gitlab-org/release/framework/issues/368
4b347a0f - Remove dead add_comment behavior from Qa::Issue
Previously this would add a comment to the QA issue using the
CommentPresenter, however this behavior was removed in
dc0047fa.
We're retaining the add_comment method, which now takes an argument,
because we plan to add comments as the corresponding release transitions
between environments.
