Add support for migrating from Gitlab (#9084) * First stab at a Gitlab migrations interface. * Modify JS to show migration for Gitlab * Properly strip out #gitlab tag from repo name * Working Gitlab migrations! Still need to figure out how to hide tokens/etc from showing up in opts.CloneAddr * Try #2 at trying to hide credentials. CloneAddr was being used as OriginalURL. Now passing OriginalURL through from the form and saving it. * Add go-gitlab dependency * Vendor go-gitlab * Use gitlab.BasicAuthClient Correct CloneURL. This should be functioning! Previous commits fixed "Migrated from" from including the migration credentials. * Replaced repoPath with repoID globally. RepoID is grabbed in NewGitlabDownloader * Logging touchup * Properly set private repo status. Properly set milestone deadline time. Consistently use Gitlab username for 'Name'. * Add go-gitlab vendor cache * Fix PR migrations: - Count of issues is kept to set a non-conflicting PR.ID - Bool is used to tell whether to fetch Issue or PR comments * Ensure merged PRs are closed and set with the proper time * Remove copyright and some commented code * Rip out '#gitlab' based self-hosted Gitlab support * Hide given credentials for migrated repos. CloneAddr was being saved as OriginalURL. Now passing OriginalURL through from the form and saving it in it's place * Use asset.URL directly, no point in parsing. Opened PRs should fall through to false. * Fix importing Milestones. Allow importing using Personal Tokens or anonymous access. * Fix Gitlab Milestone migration if DueDate isn't set * Empty Milestone due dates properly return nil, not zero time * Add GITLAB_READ_TOKEN to drone unit-test step * Add working gitlab_test.go. A Personal Access Token, given in env variable GITLAB_READ_TOKEN is required to run the test. * Fix linting issues * Add modified JS files * Remove pre-build JS files * Only merged PRs are marged as merged/closed * Test topics * Skip test if gitlab is inaccessible * Grab personal token from username, not password. Matches Github migration implementation * Add SetContext() to GitlabDownloader. * Checking Updated field in Issues. * Actually fetch Issue Updated time from Gitlab * Add Gitlab migration GetReviews() stub * Fix Patch and Clone URLs * check Updated too * fix mod * make vendor with go1.14 Co-authored-by: techknowlogick <techknowlogick@gitea.io> Co-authored-by: 6543 <6543@obermui.de> Co-authored-by: Lauris BH <lauris@nix.lv> Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com>
