Implement Multipleslave

This patch implement multiple slave support.
Instead of having a maximum of one master and one slave in one docker
image, it is now possible to have multiple slave accross several docker
host.

For helping this change, a new boards.yaml format is introduced (See
README.md for details)
Note that tokens.yaml is also squashed in boards.yaml
