replaced the old cargo task with new tasks for easier remote deployment.

Deployment now splitted into different Environments, Containernames and users to solve testing/deployment conflicts.
The users need to be unique!

Example:
Hans deploys his testing under http://137.226.58.11/HansTethys and Tim under http://137.226.58.11/TimTethys while the real deployment of the master is http://137.226.58.11/Tethys
