[JIRA] (OVIRT-1704) Add a job to update/modify secrets file

Add a job to update/modify secrets file --------------------------------------- Key: OVIRT-1704 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-1704 Project: oVirt - virtualization made easy Issue Type: New Feature Reporter: Daniel Belenky Assignee: infra We need to have a proper way to update/modify the secrets file which is stored in our Jenkins server. The alternative is having to add a way to download then update locally and upload again. If we choose to allow downloading the file, we need to make it convenient and safe so that users which are unauthorized won't be able to download it.
