Instance loses port attachment on template update

[Fabrizio Soppelsa]

Can we backport the fix for https://bugs.launchpad.net/heat/+bug/1393376 to Juno?

[Sergey Kraynev (skraynev)]

According all comments related with issue, I can say, that you may backport this patch and it should works only in case, if you also fix bug in nova:

OS::Neutron::Port default replacement_policy=AUTO

Now that nova bug 1158684 has been fixed heat can assume that a port
won't be deleted by nova during a stack update.

REPLACE_ALWAYS as a default caused its share of issues, including
servers not handling the port churn on stack updates.

REPLACE_ALWAYS is left as an option for standalone heat orchestrating
older OpenStack releases.
