[openstack-dev] Dynamically adding Extra Specs

I had a few queries regarding adding extra specs for VM requests.

According to my understanding if I want to add extra specs to requests then
I need to change that in different flavors adding those capabilities by
setting them in the flavors. But if the requests that I get have varying
values for those extra capabilities then it seems to create an issue as the
values in the flavors are static. Please correct me if I'm wrong.

So I wanted to know as to how I could dynamically add those extra specs
best suiting each request. Is there a way of mentioning the extra specs
everytime I spawn a VM through the nova cli? Setting and unsetting the
extra specs everytime I spawn VM's according to my need would be quite
inefficient as it makes changes to the database.
