Configure additional DHCP host records for hybrid scenarios

Full routing solution for hybrid scenarios involving virtual-media
BMO, requires extra host record for hypervisor host pointing out
to ocpbm bridge IP.

Add a playbook to create this record, which can be applied as a
post_infra hook. Note that neither _vm_records, nor
cifmw_dnsmasq_host_record can't be used for this currently.
