Continuous Integration for leap_platform

It would be really good to have sth like CI for leap_platform. I.e. a system which iterate on a regular basis:

• check out latest leap_cli & leap_platform development branch
• deploys it to (vagrant ? kvm ?) VMs, beeing reset to a fresh state on each deploy
• complains about deploy errors
