GitHub Importer - Migrate merge request edited events

Problem to solve

When migrating projects from GitHub to GitLab, the pull requests are imported as merge requests, including any comments. However, any history/events are not migrated over. This means that, after the migration, the users would not be able to see who added/removed labels, milestones, assignees, etc.

For some users this is a dealbreaker that would prevent them from migrating to GitLab.

Proposed solution

During project import from GitHub, for each imported merge request, check if any events of type edited exist for that merge request and create corresponding events in GitLab.

Screenshots

These images illustrate the expected result in GitLab for each event in GitHub:
