Enhance official docker image

See my comment, but I did more !

Changelog

• do not set timezone to Paris, keep it Universal, use env DEBIAN_FRONTEND var instead
• use text file to store system deps package list
• OTB version is ARG
• remove .run file after install (compressed image is now 350Mo)
• avoid use of entrypoint : symlink python lib during build, use ENV
• add missing lib to make GUI work (mapla, monteverdi also seems to work with the correct docker run command)

To do : add command example to run simple container or GUI container. Also may be use tag latest so we don't need to specify version

docker run -it orfeotoolbox/otb:8.0
docker run -it -e DISPLAY=$DISPLAY -v /tmp/.X11-unix/:/tmp/.X11-unix/ --device=/dev/dri:/dev/dri orfeotoolbox/otb:8.0 monteverdi

@vidlb Thank you for your contribution, this indeed was a first version of the docker file, it is at the moment in a "beta" state, enhancements are welcome! the CI is currently down due to a CDASH problem, once we have resolved this problem I will launch the pipeline again and merge after a review
