Database migration for caching has_confluence on project_settings

See merge request gitlab-org/gitlab!35485

Similar to other integrations that are tested for on the side nav,
(`has_external_wiki` and `has_external_issue_tracker`) this change adds
a new boolean column to `projects` to allow caching the  status of the
new confluence integration directly on the project as `has_confluence`.
