[JIRA] (OVIRT-2633) Add posibility to remove changes from change queue before change, which actually fixes the issue

Add posibility to remove changes from change queue before change, which actually fixes the issue ------------------------------------------------------------------------------------------------ Key: OVIRT-2633 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-2633 Project: oVirt - virtualization made easy Issue Type: New Feature Components: Change Queue Reporter: Martin Perina Assignee: infra Let's have a patch P1, which created an issue and failed verification in change queue. Until a fix is prepared and merged as P10, there were merged other patches P2 - P9. Because P10 is merged as last, it contains all previous changes. And because we already know that P2 - P9 will fail, there is no reason to verify those changes and there should be a way how to remove them from the change queue, so P10 can be verified as soon as possible. Otherwise we are wasting valuable recources.
