CI: Specify project id and masterbranch manifest, add variable for the ci rev
- The master branch manifest needs to be specified here, as the kirkstone branch includes the same files and needs to use kirkstone as master branch manifest
- The project id needs to be specified here, as the 'manifest.yml' will be included in multiple manifest repos with different ids.
- Putting the gitlab-ci-rev into a variable allows it to use it in further ci steps. The 'deploy-gitlab-cy' step of the gitlab-ci repo should update this value as well, as a plain substitution of the hash is used.
