[JIRA] (OVIRT-892) Allow for optional bind mounts in Standard-CI

Allow for optional bind mounts in Standard-CI --------------------------------------------- Key: OVIRT-892 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-892 Project: oVirt - virtualization made easy Issue Type: Improvement Reporter: Barak Korren Assignee: infra Standard-CI as supported a *.mounts file for a while. The way it works is that it fails if something it tries to mount does not exist. We recently changed it (in OVIRT-751) so that if something that it tries to mount does not exist, it create an empty directory and mounts it instead. We want to change the behaviour to make it more controllable so that we can specify in the mount file what to do if the thing we want to mount does not exist (And also what it should be, directory, file or a device), there are a few options: # Fail - what it used to do # Create what it needs - what it does now # Just ignore and not mound Option #3 is useful for situation where you mount sockets in order to connect to services on the host (Like Docker or Libvirt). If the bound mount is optional - we could gracefully handle the situation where the service is not running on the host by installing and running it from within the Standard-CI script.
