If heat is enabled, replace nova flavors.

All heat users will need to run heat/tools/nova_create_flavors.sh as an admin
user. This change runs nova_create_flavors.sh if heat is enabled.

This saves the hassle of switching to an admin user and running this every time
devstack is started.

Flavors are changed in heat_init, so heat_init is deferred until after nova
is running.
