Remove import columns from projects table In https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/21497, we migrated all project import data into a separate table, `project_import_data`. In addition, we also added: ``` ignore_column :import_status, :import_jid, :import_error ``` In https://gitlab.com/gitlab-com/gl-infra/production/issues/908, we observed some of these `import_error` columns consumed megabytes of error backtraces and caused slow loading of projects whenever a `SELECT * from projects` query loaded the row into memory. Since we have long migrated away from these columns, we can now drop these columns entirely. 2019-06-19 14:06:47 -04:00			`---`
