datasource/gitlab_projects: Allow to get archived and unarchived repositories. Closes #452
This change makes use of the deprecated d.GetOkExists()
function to
check if a boolean attribute has been set by the user or not.
AFAIK, it's the only way to achieve that in the SDK v2. It doesn't seem
to go anywhere without a proper replacement.
