Builds and publishes Docker images from Travis, resolves #14

[daniel-j-h]

For https://github.com/moabitcoin/ig65m-pytorch/issues/14: this sets up Travis to

• build latest CPU and GPU Docker images for master
• build CPU and GPU Docker images for every tag we commit and push

Todo

• [x] Set up Docker registry account
• [x] Set up Docker registry credentials on Travis CI/CD as env vars

Once we have this users can e.g. extract video features via

docker run --runtime=nvidia -v $PWD:/data moabitcoin/ig65m-pytorch:latest-gpu \
    extract /data/myvideo.mp4 /data/myfeatures.npy

without any other installation steps required! :tada:

Added encrypted docker credentials; we should be good now with the integration: for commits to master and all tags Travis builds docker images, and then pushes to docker hub. Let's try this!

Looks all good!

Just pushed tag v1.1.0-rc1 and Travis built and pushed for us Docker images

• https://hub.docker.com/r/moabitcoin/ig65m-pytorch/tags
• https://travis-ci.org/moabitcoin/ig65m-pytorch/builds/597803963

Let's get this in! :rocket:
