[openstack-dev] [savanna] Choosing provisioning engine during cluster launch

Today Savanna has two provisioning engines, heat and old one known as 'direct'.
Users can choose which engine will be used by setting special parameter in 'savanna.conf'.
I have an idea to give an ability for users to define provisioning engine
not only when savanna is started but when new cluster is launched. The idea is simple.
We will just add new field 'provisioning_engine' to 'cluster' and 'cluster_template'
objects. And profit is obvious, users can easily switch from one engine to another without
restarting savanna service. Of course, this parameter can be omitted and the default value
from the 'savanna.conf' will be applied.
Is this viable? What do you think?
