Summary

Commit message:
Marked ports not used by gitlab 10.6 anymore as deprecated.

I set commit information accordingly.

Test Plan

Was tested by upgrade to gitlab 10.6.x.
Ports are not used by and other port, so they are save to remove them, but give users at least one month time to react on this.
