One use-case I've seen for this sort of thing is someone that has multiple 
geographically-separate clouds, and maybe they want to run the same heat stack 
in all of them.

So they can use global glance/keystone, but they need to ensure that they have 
the right flavor(s) available in all the clouds.  This needs to be done by the 
admin user, so it can't be done as part of the normal user's heat stack.

Something like "create a keypair in each of the clouds with the same public key 
and same name" could be done by the end user with some coding, but it's 
convenient to have a tool to do it for you.
