The way heat-native was implemented, we couldn't disable it.
And when disabled, it was not working.
- operators can now pass: --heat-native=False or configure
heat_native=False in undercloud.conf, then heat native will actually be
disabled.
- 'latest' tag doesn't exist for centos-binary-heat-all so we default
to current-tripleo with is a safe default for us.
- when the heat_all container is done, it returns 137 (kill -9) which is
good but we don't want to fail on that.
