[JIRA] (OVIRT-2592) Allow caching directories in the datacenter

Allow caching directories in the datacenter ------------------------------------------- Key: OVIRT-2592 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-2592 Project: oVirt - virtualization made easy Issue Type: Improvement Reporter: Roman Mohr Assignee: infra What? Sometimes jobs create huge artifacts or need to download a lot in order start building. For instance Maven, glide or bazel download a lot before they can build. These tools also include their own checks to ensure that the content of a cached folder is in-sync. It is helpful if people can specify directories to cache. Normally it makes sense to have options to allow a cache-per-build-branch. When a PR is merged into this branch the cache from that branch is used. There are very rare conditions where it is needed to clear such a cache. A UI-Button to do so is helpful. Just to higlight the difference to e.g. container whitelist: This is about caching in the cluster, not in a build-slot.
