Fix quota increase to target cloud

Quota increase from PR #1412 was applied to the pre-adoption
TripleO cloud via SSH, but post-adoption instance creation
happens on the new adopted OpenShift-based cloud via oc exec.

Since these are separate deployments with independent quotas,
the adopted cloud still has default quota of 10, causing HTTP
403 errors when creating test-baremetal-post-adoption instance.

Add quota increase in nova_verify.yaml targeting the adopted
cloud (oc exec openstackclient) immediately before instance
creation, ensuring quota headroom exists in the correct
environment.
