Check RS for virtualized OpenStack/Yardstick

Draft for env requirements reading and validation
Script can be run from tools/virt_ci_rampup.sh. First requirement file is
parsed/stored. This file must be created in ahead and named as
'infra_deploy.yaml'. Then separate ansible role is used to validate
resources. Ansible-role fails if there is not enough resources on the host
for cpu, ram, disk space.
