Deprecated options

--projectFilter

This option has been introduced to have the hability to filter gitlab.com projects
while listing projects at API level.

--orgs and --users will provide a better control for this use case. --ignore, --include-if-has-file and co will provide a stronger control to complete the job.

--gitlab-namespace

The current implementation is not based on the API of the git hosting service.

--orgs option is more efficient as it provides gitlab group filtering at API level and makes it faster to filter by group on gitlab.com for example.
