added the script deboco which is able to create multiple standalone debops controllers
- it automates the creation of standalone debops controllers. A standalone debops controller is a directory that embeds: - its own ansible.debops tree (which contains ipr debops configuration, but also its secret directory) - its own virtualenv - its own reports on debops runs when perfoming operations with this controller - it simplifies some operations like applying a configuration to a new machine work related to https://bugzilla.ipr.univ-rennes.fr/show_bug.cgi?id=3713
