So the container_runtime_t type was missing because container-selinux didn't install properly, and in turn openstack-selinux couldn't find the symbols it needed either.
We need to find out what prevented the container-selinux rpm from installing correctly the first time, there probably was a "silent" error like in comment 5.
From the paste, before reinstalling container-selinux:
$ seinfo --type | grep container ro_file_ t
container_file_t
container_
container_t
