ClusterResourceQuota usage is above project quota in OpenShift Container Platform

Issue

• In our OCP 3.9 cluster customers experience an interesting issue with CRQ from time to time. It mostly happens that when build or deployment is triggered in a project that has project quota setup and belongs to clusterresourcequota. There are free resources both on project level and on the CRQ level. After the build/deployment is triggered, the usage of CPU goes up for this single project in CRQ. It gets higher than what is allowed by the project quota. The pod can't be started due to scheduling problem - the quota limit has been reached.
• In case the project quota exceed it's resources (hitting the limit), the pod or activity can't run (as expected). But the usage in the ClusterResourceQuota continues to grow (not sure where this growth is coming from) and eventually will reach its limit, which has an impact on all other project(s). As ClusterResourceQuota is used up, all other project(s) fail to run any activity.
