Build the Whole eGovId in one environment (docker file)

Update the docker structure, so that a single Docker image is built.

The CI should be mostly set up.

It will require that no DSUs are build during the build-all command. see glass-wallet-workspace to see how to acomplish this (especially for DSU explorer).

From this point onwards all apps from from the market (and therefore must be published beforehand).

I updated the docker file to already use the prebuilt base image (from the node-postgres-docker repository). To use locally you'll have to dogin to the docker registry: docker login -u username -p password registry.unitech.eu.

the username is the email you used to register (and the password is the matching password)

It's still not fully working/tested since the build-all command needs to be changed/

Also I think a new startup script will be required to start all services
