[kolla] broken images pushed

We have merged publisher for aarch64 images and it turned out that it was done wrong way. Today both x86-64 and aarch64 images got published at same time so "kolla/debian-source-*" images are broken: 08:55 (0s) hrw@puchatek:~$ docker run --rm -it kolla/debian-source-heat-engine:master bash standard_init_linux.go:211: exec user process caused "exec format error" This is result of aarch64 image overwriting x86-64 one. We reverted arm64 publisher and will work on it in January. Sorry for potential problem.
