Rename occurences of project "tags" to "topics"
In https://gitlab.com/gitlab-org/gitlab-ce/issues/54167 (https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/24219) we renamed project "tags" to "topics".
As a part of https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/24219, we renamed some occurrences but not everything was picked up. For example, there are still references to project.tag_list
.
I noticed there are a few references to "tag" and "tag_list" in the backend that don't relate to only projects. For example, parts of CI use "tags".
We should update all the project "tag" references to "topics" on the backend.
Just to be clear, I don't think this should happen because there are other references to "tag" in different resources, that's just an extra win, the main reason is that project tags are now "topics".
