[Linaro-validation] moving test-definitions repository to github

Hi,

In order to make it easier to contribute we decided to move test-definitions.git to github. Github repository will be the 'master' one and it will be synced back to git.linaro.org. So if you're using the git.linaro.org repository for running tests, nothing changes for you. There is no plan to remove this repository. However we won't be able to accept patches through gerrit review now. All patches should be submitted as github pull requests.

To sum up: 1. git.linaro.org/qa/test-definitions.git is now read-only 2. github.com/Linaro/test-definitions.git is where the changes can be submitted 3. all changes from github/Linaro/test-definitions.git are synced back to git.linaro.org/qa/test-definitions.git
