Track group access level of user during imports

Carla Dragorequested to merge
378867-track-access-level into master

What does this MR do and why?

These changes add event tracking for the user's role when importing groups and projects with:

  • file-based project import (gitlab_project)
  • from GitHub (github)
  • with Gitlab Migration (bulk_import_group)
  • or from bitbucket (bitbucket).

This will assist in understanding which roles are using import features.
