Switches to use ephemeral Heat by default for all overcloud operations
and defaults enable_heat to False in undercloud.conf. Stack data will be
migrated to the ephemeral Heat model (to use the consistent working
directory) as part of the upgrade with the inclusion of the depends-on.
To improve the UX when using ephemeral Heat, "stack resource list" is
now run after "stack failures list" automaticaly in the case of Heat
stack failures.
