Refactor gitlab-ci to use a custom deployment
Before submitting this Merge Request I change all the references of the cern-sso-proxy to use the stable
tag in:
- In its own repo
- In the template deployed with puppet
- In existing apps using the cern-sso-proxy Grafana template is still missing as I will do it today with Ignacio from DB to show him how the CI works.
The new deployment is based on what was discussed in https://its.cern.ch/jira/browse/CIPAAS-163
