Use heat devstack plugin

Now that heat is available as a devstack plugin, we should
use it. In-tree devstack code for heat is planned to be
removed soon[1].

And also, this patch remove `update_heat_policy` function
in devstack plugin. Because fetching global stack list is
already option to use in Magnum.
