This sets up all the basics for importing Phabricator tasks into
GitLab issues.
To import all tasks from a Phabricator instance into GitLab, we'll
import all of them into a new project that will have its repository
disabled.
The import is hooked into a regular ProjectImport setup, but similar
to the GitHub parallel importer takes care of all the imports itself.
In this iteration, we're importing each page of tasks in a separate
sidekiq job.
The first thing we do when requesting a new page of tasks is schedule
the next page to be imported. But to avoid deadlocks, we only allow a
single job per worker type to run at the same time.
For now we're only importing basic Issue information, this should be
extended to richer information.
These are backend changes.
Use Vue for the import feature UI for "githubish"
providers (GitHub and Gitea).
Add "Go to project" button after a successful import.
Use CI-style status icons and improve spacing of the
table and its component.
Adds ETag polling to the github and gitea import
jobs endpoint.
The reason is that Gitea plan to be GitHub-compatible so it makes sense
to just modify GitHubImport a bit for now, and hopefully we can change
it to GitHubishImport once Gitea is 100%-compatible.
