Official docker image/containers for OpenCV

[jinay1991]

This Issue is a Feature Request for official OpenCV docker container images in hub.docker.com with varieties like -

1. Developer container (holds CPU compiled libraries/headers) - docker
2. Developer container (holds GPU compiled libraries/headers) - nvidia-docker
3. Developer Python container (holds python wrappers) - Useful for CI or quick debug

These should be available for each versions (release/nightly) to allow developers test their code in multiple version of OpenCV without really changing the environment as they can run multiple containers at same time. Also support for various OS images would be really appreciated here (i.e. Debian, CentOS, Ubuntu)

This will save deployment timeline for many developers and at the same time OpenCV CI can get benefit from this. This will also avoid extra efforts in maintaining/creating custom docker containers for each developers and they can rely on this baseline image.

OpenCV CI

Development images are usually different from testing ones. Maintaining of one more distribution channel will only add effort to the team. Most of package managers have OpenCV so it's already the simplest way to get the libraries compatible with other packages for your version of OS.

I think instead it is useful when you need to contribute to Opencv itself and also for IDE/github codespace integration. I.e. see https://github.com/microsoft/vscode-dev-containers/tree/master/repository-containers/github.com/tensorflow/
