fix(docker): minimal docker images (#942)

* alpine image and simpler circleci build

* include rsync

* run in correct container

* more steps to workflow

* run npm install with sudo

* git sha tag for now

* find the built image

* persist built image between workflows

* conditional tagging

* fix tag

* no need for additional scripts

* remove get logs script

* remove git from final binary

* clean up config and get reports and logs from containers

* export the env var

* hard coded container name

* fix syntax error on docker cp

* fix stupid typo

* fix(ci): build docker on tag release

* docs(badge): adds circleci build status badge
