This change adds platform-specific Dockerfiles and a Makefile
to build the toolkit-container images.
This image builds the container-config commands from the tools
directory and installs the components of the NVIDIA Container Toolkit
directly from the nvidia-container-toolkit and libnvidia-container*
packages in the dist directory.
This includes make targets for the centos7, centos8, ubuntu18.04,
and ubi8 container-toolkit images as well as the container tests
make targets implemented in the contianer-config repository.
