Add post_infra hook processing to create-infra.yml

[renjingxiao]

The adoption deploy-infra job uses create-infra.yml which did not process post_infra hooks. This meant hooks like vlanprovider_mtu (which sets the hypervisor trunk bridge MTU) only ran in greenfield via cifmw_setup but never in adoption. Adding run_hook after deploy_layout ensures the trunk bridge MTU is set before VMs boot.
