Publish Ubuntu Build Service images on snapshots.linaro.org

[Fathi Boudra]

Images from https://ci.linaro.org/jenkins/view/Ubuntu Build Service/ should be published on snapshots.linaro.org.
The bug is incomplete as we need to specify destination layout on snapshots.linaro.org.

[Fathi Boudra (fboudra)]

Destination layout proposal:

* hwpacks - http://snapshots.linaro.org/precise-hwpacks/${boardname}/${build_number}
e.g. http://snapshots.linaro.org/precise-hwpacks/lt-panda/12/

* ospack - http://snapshots.linaro.org/precise-images/${image_type}/${build_number}
e.g. http://snapshots.linaro.org/precise-images/nano/14/

Final destination layout:
http://snapshots.linaro.org/precise/hwpacks/${boardname}/${build_number}
http://snapshots.linaro.org/precise/hwpacks/lt-panda/12/
http://snapshots.linaro.org/precise/images/${image_type}/${build_number}
http://snapshots.linaro.org/precise/images/nano/14/
