Improve build and scripts (#30)

* Use absolute path rather than relative path in scripts

* Remove src/bitBetter/.keys/cert.cert

* Build licenseGen in Docker
This way we don't have to install dotnet sdk on the host

* Build bitBetter in Docker
This way we don't have to install dotnet sdk on the host

* Change DIR in run.sh to point to the project root

* Replace echo in Dockerfiles by set -x and set -e

* Use same Dockerfile for api and identity images

* Update README.md

* Update CircleCI config
The Docker Executor can't mount volume.
