How to specify limits and requests for cpu and memory in OpenShift

Issue

• How to specify limits.cpu, limits.memory, requests.cpu, requests.memory for builds or for any workload?

• When applying resourcequota at project level builds fails with below error :

  Error creating: pods "test-php-1-build" is forbidden: Failed quota: ludo-quota: must specify limits.cpu,limits.memory,requests.cpu,requests.memory
