[JIRA] (OVIRT-1672) Add support for secrets to the pipeline STDCI jobs

Add support for secrets to the pipeline STDCI jobs -------------------------------------------------- Key: OVIRT-1672 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-1672 Project: oVirt - virtualization made easy Issue Type: Improvement Components: oVirt CI Reporter: Barak Korren Assignee: infra The secrets syntax is currently supported only by the Freestyle-based STDCI jobs. We need to add support for the pipeline jobs. As part of the work on this, we need to move the code that requires project-specific env vars (like 'PROJECT') out of the '{{global_setup.sh}}' script which can run at an early stage where we don't know which project are we testing yet, and into a project-specific setup script.
