[rdo-list] RDO CI hardware requirements for CentOS altarch

[Xiandong Meng]

OK, i mean on the same time, how many concurrent CI jobs may be running?
For example, at peak load, will weirdo-master-promote-packstack-scenario001
<https://ci.centos.org/view/rdo/view/promotion-pipeline/job/weirdo-master-promote-packstack-scenario001/>
, weirdo-master-promote-packstack-scenario002 ,
<https://ci.centos.org/view/rdo/view/promotion-pipeline/job/weirdo-master-promote-packstack-scenario002/>
weirdo-master-promote-packstack-scenario003
<https://ci.centos.org/view/rdo/view/promotion-pipeline/job/weirdo-master-promote-packstack-scenario003/>
run at the same time? Or they will run in sequence by design?
