Map Jira author and assignee to a gitlab User
Now we store real Jira issue author and assignee in metadata section of GitLab issue. We should store the information in the correct fields (author, assignee) and use Jira user mapped to GitLab user.
As the first iteration, we should simply take the information in the jira issue json and map the users to GitLab users based on their emails. Only users, who are project members, should be mapped. If a user is not found for an email, it will be logged. Issue won't be not assigned and the issue author remains default (project.creator
now and import owner once #215569 (closed) is fixed - MR in review).
