overhaul of Dockerfile and run.sh

[maldex]

All tough I still don't get why fly sync can work before fly login, the current image only seems to work on ubuntu hosts. Following up issue #18 and the discussion with pull request #19, the attached proposal is an overhaul of the current build and run methods.

Essentially: run.sh

• the ENTRYPOINT directive allows for container parameters to be passed into the actual application (note: this behavior differs from CMD directive). The proposed run.sh allows for argument segretation of docker related and application related arguments. Please find a sample in the simplified run.nsx-t-install-er.sh script.
• the original flow has been kept, but 'modularized' into shell functions.
• the fly-related commands have also been rewritten into shell functions.
• the container (should) automatically detect if it's interactive (-it) and present you with a bash.
• shutdown and destruction has been refactored.
• the involved containers should not stay around and cause conflict (using --rm switch and ensuring docker-compose down was called upon graceful container termination)

Dockerfile

• split up into multiple run statements leveraging the layering during the build.
• unified downloads to wget and added minimal documentation.

So far i was able to bring the concourse pipeline for nsx-t-install up and running on a Fedora host. cheers

darn, sometimes, git and I are not friends

if someone sees this, i'm too stupid to update the content of _dockerimage/ correctly. And as it's almost 1am again, ... how would i exactly start all-over again and just contribute these four files in https://github.com/maldex/nsx-t-datacenter-ci-pipelines/tree/master/docker_image?

and can this pull request be obliterated?
