[JIRA] (OVIRT-1508) get upstream_source_collector.py script instead of embedding it

get upstream_source_collector.py script instead of embedding it --------------------------------------------------------------- Key: OVIRT-1508 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-1508 Project: oVirt - virtualization made easy Issue Type: Task Reporter: Gil Shinar Assignee: Gil Shinar We want to move to pipeline jobs in the future and in that matter we want to embed code in yamls as little as possible. The way to do it is to move the upstream_source_collector.py to a seperate script that'll be called from a jenkins step. The only embedded code will be a very short and simple code that'll get the script from upstream before actually calling it.
