Docker Files Changes

[Tonnix]

1. I've added documenting comments to flint and flint base docker files
2. I've added a sleek docker file to the mix to provide a single resource point for dockers
3. I've changed the source of boost libraries to avoid this issue: boost_1_70_0.tar.gz is Forbidden boostorg/boost#299
4. I've updated the references to FLINT.Data repository which was renamed to FLINT.Data_Preprocessing
5. I've changed the image names to correspond to the new naming standards
6. I've updated the readme to include the fact that implementation docker files are in the repository now

Hey @Tonnix - this looks awesome!

Tagging @malfrancis @mfellows @leitchy @kaskou - can we leverage this PR to address: #24

Makefiles look like the canonical way to publish images on https://hub.docker.com/u/mojaglobal. @Tonnix - do you think you could help one of the Documentation Working Group document the process of publishing a new Docker images? Including steps to promote new releases and and encouraging project maintainers to standardise their Dockerfiles to use the official base images?

Hey @Tonnix - is there any way we can help you move this along?

Hi @aornugent ,

Yes, please let me know who I can work with in the Documentation Work Group to move this along. I will also need to talk with @malfrancis or @leitchy about it
