Create image with previous version of contrib

[PuneetKohli]

We've been using your docker image for our testing and noticed our code started failing today on automated builds due to the upgrade.

We reverted to contrib-opencv-3.4.1 but that has an older version of cmake.

Can you release a version of contrib which was pushed 3 months ago in August?

I think that was contrib-opencv-3.4.2, it's currently building on docker hub should be available soon

Thanks, using this build fixed our issue!
