Enforce flavor extended parameters

OpenStack environment may have compute nodes which are using hugepages only.
Users would like to create new flavors for themselves.
Users may not know physical underlay and may omit specifying some extra parameters.
This would lead to VM creation failures and network outages.

Cloud devops should have an ability to enforce propagation of some extra params into newly created flavors.
For example:
--property hw:mem_page_size=large

Expectation:
User creates flavor by executing:
openstack flavor create --ram 1024 --vcpus 1 --public m1.small
Propertiy hw:mem_page_size=large has been propagated and added automaticaly.

This is a feature requrest.
